How to fix header in struts datagrid

[Mukul Object]

Hello All,
I am seeking for suggestions on how can we fix the header in Struts-Datagrid.

In my jsp , I have implemented struts-datagrid and showing many rows at a time.
While scrolling the page , the column-names/header of the datagrid also scroll up and down and do not remain visible to the user.

Is there any way to fix the column-name/header to the top of datagrid?

Kindly suggest any solution.

Thanks
