Could you any suggestion.

Please, refer to the following example in the datastore package:
“dhtmlxDataStore/samples/01_combinations/08_form2grid_server.html”
adding footer works well in it.

If issue still occurs for you - please, change your code to the format of the provided sample and provide with the formatted code or a complete demo, so the issue can be reproduced on our side.
