could you please inform me how to increase the height of the header of the grid.and give color to the columns.
The height of header defined by content, basically you can adjust grid’s css
dhtmlxgrid.css
div.gridbox table.hdr td {
height: 40px; // or any other necessary value.
>>and give color to the columns
You can define colors of header by using third parameter of setHeader command
dhtmlx.com/docs/products/kb/inde … er%20color
or by adding necessary value to the same css class.
