Row spanning in Angular Grid component

6 Sep 202214 minutes to read

The grid has option to span row cells. To achieve this, You need to define the rowSpan attribute to span cells in the QueryCellInfo event.

In the following demo, Davolio cell is spanned to two rows in the EmployeeName column.

Also Grid supports the spanning of rows and columns for same cells. Lunch Break cell is spanned to two rows and three columns in the 1:00 column.

import { Component, OnInit } from '@angular/core';
import { QueryCellInfoEventArgs, GridLine } from '@syncfusion/ej2-angular-grids';
import { columnSpanData, ColumnSpanDataType } from './datasource';
import { EmitType } from '@syncfusion/ej2-base';

@Component({
    selector: 'app-root',
    template: `<ejs-grid [dataSource]='data' [height]='300' [width]='width' [gridLines]='gridLines'
       [allowTextWrap]='textWrap' (queryCellInfo)='queryCellInfoEvent($event)'>
        <e-columns>
            <e-column field='EmployeeID' headerText='Employee ID' width='150' textAlign="Right" isPrimaryKey=true></e-column>
            <e-column field='EmployeeName' headerText='Employee Name' width='200'></e-column>
            <e-column field='9:00' headerText='9:00 AM' width='120'></e-column>
            <e-column field='9:30' headerText='9:30 AM' width='120'></e-column>
            <e-column field='10:00' headerText='10:00 AM' width='120'></e-column>
            <e-column field='10:30' headerText='10:30 AM' width='120'></e-column>
            <e-column field='11:00' headerText='11:00 AM' width='120'></e-column>

            <e-column field='1:00' headerText='1:00 PM' width='120'></e-column>
            <e-column field='1:30' headerText='1:30 PM' width='120'></e-column>

To disable the spanning for particular grid page, we need to use requestType from QueryCellInfo event argument.
