    Tablejs

    Tablejs is an open-source solution for displaying complex grid content in Angular. Tablejs provides high performance grids supporting millions of rows of content and enables easy integration into familiar HTML, CSS, and Javascript concepts. Look below for an example of a grid with several features enabled.

    Usage

    How to Install

    npm install --save @transunion-ui/tablejs
    

    Import Module

    import { TablejsModule } from '@transunion-ui/tablejs'

    Enable grid Functionality

    Wrap the tablejs-grid component around your table data:

    <tablejs-grid>
    	<table></table>
    </tablejs-grid>

    Designate the grid’s rows by adding the tablejsGridRow directive to the table’s rows (tr):

    <tablejs-grid>
    	<table>
    		<thead>
    			<tr tablejsGridRow></tr>
    		</thead>
    	</table>
    </tablejs-grid>

    Resize Column Functionality

    Designate which elements you would like to use as your resizable grip/handle by adding the resizableGrip directive:

    <tablejs-grid>
    	<table>
    		<thead>
    			<tr tablejsGridRow>
    				<th resizableGrip><div>Header 1</div></th></th>
    				<th>
    					<div resizableGrip></div>
    					<div>Header 2</div>
    				</th>
    			</tr>
    		</thead>
    	</table>
    </tablejs-grid>

    Note: The entire header can be used as a resizable element, but keep in mind that if you would like to enable sorting based on clicking the header, you may want to create an icon inside the header specifically for resize functionality

    The grid relies on tying classes together for resize functionality. The tablejsDataColClasses directive designates which columns a header columns should have width control over. This would be a th or td tag. Notice you can include a list of classes for header columns that span multiple columns. See the example below:

    Header 1 below resizes both Sub Header 1 and Sub Header 2 columns proportionately. To tie the table body column cells to the headers, the tablejsDataColClass directive is added. In the example below, Header 1 resizes columns with tablejsDataColClass set to class1 and class2. Sub Header 1 only changes the width of the columns containing class1 and Sub Header 2 only changes the width of the column containing class2. For greatly improved perfomance, include an initialWidth directive on each column containing the tablejsDataColClass directive so that the tablejsGrid directive does not need to access the DOM for widths on instantiation.

    <tablejs-grid>
    	<table>
    		<thead>
    			<tr tablejsGridRow>
    				<th tablejsDataColClasses="class1, class2" colspan="2" >
    					<div resizableGrip></div>
    					<div>Header 1</div>
    				</th>
    			</tr>
    			<tr tablejsGridRow>
    				<th tablejsDataColClasses="class1">
    					<div resizableGrip></div>
    					<div>Sub Header 1</div>
    				</th>
    				<th tablejsDataColClasses="class2">
    					<div resizableGrip></div>
    					<div>Sub Header 2</div>
    				</th>
    			</tr>
    		</thead>
    		<tbody>
    			<tr tablejsGridRow>
    				<td><div tablejsDataColClass="class1" initialWidth="300">Content in cell 1</div></td>
    				<td><div tablejsDataColClass="class2" initialWidth="300">Content in cell 2</div></td>
    		</tbody>
    	</table>
    </tablejs-grid>

    For proper resizing of the infinite scrolling component, include the tablejsInfiniteScroll directive on your cdk-virtual-scroll-viewport component:

    <cdk-virtual-scroll-viewport class="tall-viewport" tablejsInfiniteScroll autosize></cdk-virtual-scroll-viewport>

    Reorder Column Functionality

    To add column reorderability to a column, add the reorderCol directive:

    <tablejs-grid>
    	<table>
    		<thead>
    			<tr tablejsGridRow>
    				<th reorderCol><div>Header 1</div></th></th>
    			</tr>
    		</thead>
    	</table>
    </tablejs-grid>

    Next, create a handle for the user to pull on in order to reorder the column by adding the reorderGrip directive:

    <tablejs-grid>
    	<table>
    		<thead>
    			<tr tablejsGridRow>
    				<th reorderCol>
    					<div reorderGrip></div> 
    					<div>Header 1</div>
    				</th>
    			</tr>
    		</thead>
    	</table>
    </tablejs-grid>

    A ghost drag and drop object is displayed while dragging to reorder a column. Sometimes you may not want to show the entire column header object to display. You can filter out selected elements by passing a filter function via the dragAndDropGhostFilter directive.

    <tablejs-grid [dragAndDropGhostFilter]="dragDropFilter">
    	<table>
    		<thead>
    			<tr tablejsGridRow>
    				<th reorderCol>
    					<div reorderGrip></div> 
    					<div>Header 1</div>
    				</th>
    			</tr>
    		</thead>
    	</table>
    </tablejs-grid>

    In your component, you would write the dragDropFilter function you supplied. This example filters out all i tags.

    dragDropFilter(el: HTMLElement) {
        return (el.tagName !== 'I');
    }

    Disabling selected rows from reordering

    The reordering relies on the css grid functionality. To disable a row from reordering, simply set the grid-column-start and grid-column-end styles on the td or th tags. This is especially useful for expandable and collapsible rows.

    <tablejs-grid [dragAndDropGhostFilter]="dragDropFilter">
    	<table>
    		<tbody>
    			<tr tablejsGridRow>
    				<td reorderCol style=”grid-column-start: 1; grid-column-end: 11;“></td>
    			</tr>
    		</tbody>
    	</table>
    </tablejs-grid>
