Hello Seang,

Thank you for posting in the community.

There is not API for doing that out of the box. You should use jQuery and manipulate the igGrid DOM tree.

There are two ways to do that:

The first uses the following code:

$("#grid1").igGrid("headersTable").find('thead > tr:eq(0) > th:eq(0) > span.ui-iggrid-headertext').html("");

This code finds the leftmost column header using the igGrid headersTable API.

The second way uses the following code:

$("#grid1_Name > span.ui-iggrid-headertext").html("");

where #grid1_Name is the name of the th element and is constructed the following way:

<grid_id>_<column_key>, where <grid_id> is the id of the grid placeholder and the <column_key> is the key of the column.

Do not hesitate to  ask if you have any additional questions.
