Need Icon on header of dhtmlxgrid

headerString += “,trancheId,ioiId,img:[…/images/pot-list.gif]IOI,Alloc”;
gridPotList.attachHeader(",Account,Matches" + headerString);

but it displays the text as it is, how to get icon.

appreciate your help

Locally the same code works correctly

If issue still occurs for you - please provide any kind of sample or demo link where it can be reconstructed.

As workaround - you can use inline HTML code, as

headerString += ",trancheId,ioiId,<img src='../images/pot-list.gif'>IOI,Alloc"; gridPotList.attachHeader(",Account,Matches" + headerString);

Thanks it works great
