## Basic usage

**[app.component](../../demo-shell/src/app/app.component.ts).html**

```html
<adf-datatable 
    [data]="data">
</adf-datatable>
```

**[app.component](../../demo-shell/src/app/app.component.ts).ts**

```ts
import { ObjectDataTableAdapter }  from '@alfresco/adf-core';

@Component({...})
export class DataTableDemo {
    data: ObjectDataTableAdapter;

    constructor() {
        this.data = new ObjectDataTableAdapter(
            // data
            [
                {id: 1, name: 'Name 1'},
                {id: 2, name: 'Name 2'}
            ],
            // schema
            [
                {
                    type: 'text',
                    key: 'id',
                    title: 'Id',
                    sortable: true
                },
                {
                    type: 'text',
                    key: 'name',
                    title: 'Name',
                    cssClass: 'full-width',
                    sortable: true
                }
            ]
        );
    }
}
```

### Setting the rows and column schema

You can set rows and columns in the [`ObjectDataTableAdapter`](../../lib/core/datatable/data/object-datatable-adapter.ts) as shown below:

```ts
import { ObjectDataTableAdapter }  from '@alfresco/adf-core';

@Component({...})
export class DataTableDemo {
    data: ObjectDataTableAdapter;

    constructor() {
        this.data = new ObjectDataTableAdapter(
            // data
            [
                {id: 1, name: 'Name 1'},
                {id: 2, name: 'Name 2'}
            ],
            // columns
            [
                {
                    type: 'text',
                    key: 'id',
                    title: 'Id',
                    sortable: true
                },
                {
                    type: 'text',
                    key: 'name',
                    title: 'Name',
                    cssClass: 'full-width',
                    sortable: true
                }
            ]
        );
    }
}
```

```html
<adf-datatable 
    [data]="data">
</adf-datatable>
```

You can also set rows and use an HTML-based schema declaration as shown below:

```ts
import { ObjectDataTableAdapter }  from '@alfresco/adf-core';

@Component({...})
export class DataTableDemo {
    data: ObjectDataTableAdapter;

    constructor() {
        this.data = new ObjectDataTableAdapter(
            // data
            [
                {id: 1, name: 'Name 1'},
                {id: 2, name: 'Name 2'}
            ],
            []
        );
    }
}
```

```html
<adf-datatable [data]="data">
    <data-columns>
        <data-column key="icon" type="image" [sortable]="false"></data-column>
        <data-column key="id" title="Id"></data-column>
        <data-column key="createdOn" title="Created"></data-column>
        <data-column key="name" title="Name" class="full-width name-column"></data-column>
        <data-column key="createdBy.name" title="Created By"></data-column>
    </data-columns>
</adf-datatable>
```

You can also set rows to the [`ObjectDataTableAdapter`](../../lib/core/datatable/data/object-datatable-adapter.ts) and set columns as an input as shown below :

```ts
import { ObjectDataTableAdapter }  from '@alfresco/adf-core';

@Component({...})
export class DataTableDemo {
    data: ObjectDataTableAdapter;
    schema: any;

    constructor() {
        this.data = new ObjectDataTableAdapter(
            // data
            [
                {id: 1, name: 'Name 1'},
                {id: 2, name: 'Name 2'}
            ],
            []
        );
        // columns
        this.schema =
            [
                { 
                    type: 'text', 
                    key: 'id', 
                    title: 'Id', 
                    sortable: true 
                },
                {
                    type: 'text', 
                    key: 'name', 
                    title: 'Name', 
                    sortable: true
                }
            ];
    }
}
```

```html
<adf-datatable
    [data]="data"
    [columns]="schema">
</adf-datatable>
```

You can also set rows and columns through inputs as shown below :

```ts
import { ObjectDataTableAdapter }  from '@alfresco/adf-core';

@Component({...})
export class DataTableDemo {
    rows: any;
    schema: any;

    constructor() {
        // data
        this.rows =
            [
                {id: 1, name: 'Name 1'},
                {id: 2, name: 'Name 2'}
            ];
        // columns
        this.schema =
            [
                { 
                    type: 'text', 
                    key: 'id', 
                    title: 'Id', 
                    sortable: true 
                },
                {
                    type: 'text', 
                    key: 'name', 
                    title: 'Name', 
                    sortable: true
                }
            ];
    }
}
```

```html
<adf-datatable
    [rows]="rows"
    [columns]="schema">
</adf-datatable>
```

### [Transclusions](../user-guide/transclusion.md)

You can add [Data column component](data-column.component.md) instances to define columns for the
table as described in the usage examples and the [Customizing columns](#customizing-columns) section.

You can also supply a `<adf-no-content-template>` or an
[Empty list component](empty-list.component.md) sub-component to show when the table is empty:

```html
<adf-datatable ...>
    <adf-no-content-template>
        <!--Add your custom empty template here-->
        <ng-template>
            <h1>Sorry, no content</h1>
        </ng-template>
    </adf-no-content-template>
</adf-datatable>
```

```html
<adf-datatable ...>        
    <adf-empty-list>
        <adf-empty-list-header>"'My custom Header'"</adf-empty-list-header>
        <adf-empty-list-body>"'My custom body'"</adf-empty-list-body>
        <adf-empty-list-footer>"'My custom footer'"</adf-empty-list-footer>
        <ng-content>"'HTML Layout'"</ng-content>
    </adf-empty-list>
</adf-datatable>
```

Another useful transclusion is the `<adf-loading-content-template>`, which is shown
while the data for the table is loading:

```html
<adf-datatable ...>
    <adf-loading-content-template>
        <ng-template>
            <!--Add your custom loading template here-->
            <mat-progress-spinner
                class="adf-document-list-loading-margin"
                [color]="'primary'"
                [mode]="'indeterminate'">
            </mat-progress-spinner>
        </ng-template>
    </adf-loading-content-template>
</adf-datatable>
```

```js
    isLoading(): boolean {
        //your custom logic to identify if you are in a loading state 
    }
```

Note that you can use both the `<adf-no-content-template>` and the `<adf-loading-content-template>`
together in the same datatable.

## Details

### Supplying data for the table

The column layout and row data are supplied to the table using an object that implements the
[`DataTableAdapter`](../../lib/core/datatable/data/datatable-adapter.ts) interface. This interface hides the internal details of the class that provides
the data, which gives a lot of flexibility in how the data can be stored and accessed. The DataTable
library includes a standard adapter class called [`ObjectDataTableAdapter`](../../lib/core/datatable/data/object-datatable-adapter.ts) that is useful in many
common cases. See the [`DataTableAdapter`](../../lib/core/datatable/data/datatable-adapter.ts) for full details about the interface and the [`ObjectDataTableAdapter`](../../lib/core/datatable/data/object-datatable-adapter.ts) class.

### Customizing columns

You can define custom HTML templates for columns and also add tooltips, automatic column title translation and other features. See the [Data Column component](data-column.component.md) page
for more information.

### DataTable DOM Events

Below are the DOM events emitted by the DataTable component.
These events bubble up the component tree and can be handled by any parent component.

| Name | Description |
| ---- | ----------- |
| row-click | Raised when user clicks a row |
| row-dblclick | Raised when user double-clicks a row |
| row-select | Raised after user selects a row |
| row-unselect | Raised after user unselects a row |
| row-keyup | Raised on the 'keyup' event for the focused row. |
| sorting-changed | Raised after user clicks the sortable column header. |

For example:

```html
<root-component (row-click)="onRowClick($event)">
    <child-component>
        <adf-datatable></adf-datatable>
    </child-component>
</root-component>
```

```ts
onRowClick(event) {
    console.log(event);
}
```

![](../docassets/images/datatable-dom-events.png)

### Card view

Set the `display` property to "gallery" to enable Card View mode:

```html
<adf-datatable
    [data]="data"
    [display]="'gallery'">
</adf-datatable
```

![card-view](../docassets/images/document-list-card-view.png)

### Using events

#### row-keyup DOM event

Emitted on the 'keyup' event for the focused row. 

This is an instance of `CustomEvent` with the `details` property containing the following object:

```ts
row: DataRow,
keyboardEvent: KeyboardEvent,
sender: any
```

#### rowClick event

Emitted when the user clicks a row.

Event properties:

```ts
sender: any     // DataTable instance 
value: DataRow, // row clicked
event: Event    // original HTML DOM event
```

Handler example:

```ts
onRowClicked(event: DataRowEvent) {
    console.log(event.value);
}
```

This event is cancellable. You can use `event.preventDefault()` to prevent the default behavior.

#### rowDblClick event

Emitted when the user double-clicks a row.

Event properties:

```ts
sender: any     // DataTable instance 
value: DataRow, // row clicked
event: Event    // original HTML DOM event
```

Handler example:

```ts
onRowDblClicked(event: DataRowEvent) {
    console.log(event.value);
}
```

This event is cancellable. You can use `event.preventDefault()` to prevent the default behavior.

#### showRowContextMenu event

Emitted before the context menu is displayed for a row.

Note that the DataTable itself does not populate the context menu with items.
You can provide all necessary content via the handler.

Event properties:

```ts
value: {
    row: DataRow,
    col: DataColumn,
    actions: []
}
```

Handler example:

```ts
onShowRowContextMenu(event: DataCellEvent) {
    event.value.actions = [
        { ... },
        { ... }
    ]
}
```

This event is cancellable. You can use `event.preventDefault()` to prevent the default behavior.

The DataTable will automatically render the supplied menu items.

See the [ContextMenu](https://www.npmjs.com/package/ng2-alfresco-core)
documentation for more details on the format and behavior of context actions.

#### showRowActionsMenu event

Emitted before the actions menu is displayed for a row.
Requires the `actions` property to be set to `true`.

Event properties:

```ts
value: {
    row: DataRow,
    action: any
}
```

Note that the DataTable itself does not populate the action menu with items.
You can provide all necessary content via the handler.

This event is cancellable. You can use `event.preventDefault()` to prevent the default behavior.

#### executeRowAction event

Emitted when the user executes a row action.

This usually accompanies a `showRowActionsMenu` event. 
The DataTable itself does not execute actions but provides support for external
integration. If actions are provided using the `showRowActionsMenu` event
then `executeRowAction` will be automatically executed when the user clicks a
corresponding menu item.

```html
<adf-datatable
    [data]="data"
    [multiselect]="multiselect"
    [actions]="true"
    (showRowActionsMenu)="onShowRowActionsMenu($event)"
    (executeRowAction)="onExecuteRowAction($event)">
</adf-datatable>
```

```ts
import { DataCellEvent, DataRowActionEvent } from '@alfresco/adf-core';

onShowRowActionsMenu(event: DataCellEvent) {
    let myAction = {
        title: 'Hello'
        // your custom metadata needed for onExecuteRowAction
    };
    event.value.actions = [
        myAction
    ];
}

onExecuteRowAction(event: DataRowActionEvent) {
    let args = event.value;
    console.log(args.row);
    console.log(args.action);
    window.alert(`My custom action: ${args.action.title}`);
}
```

![](../docassets/images/datatable-actions-ui.png)

![](../docassets/images/datatable-actions-console.png)

You can use any payloads for row actions. The only requirement for the objects is that they
must have a `title` property.

When an action is selected in the dropdown menu, the DataTable invokes the `executeRowAction` event.
Use this to handle the response, inspect the action payload (and all custom properties defined
earlier), and perform the corresponding actions.
