This sample demonstrates the Grid component with the column spanning feature. In this sample, we have spanned multiple adjacent cells together.
Grid allows to span the multiple adjacent cells. In QueryCellInfo event, you can define the colSpan attribute to span the cells.
In this demo, Employee Davolio doing testing from 9.00 AM to 10.00 AM, so that the cells have been spanned and Employee Buchamann doing development work from 9.30 AM to 11.00 AM, so that the cells have been spanned.
