jQuery Grid Plugin - jqGrid

Hi Guys,

I'm trying to load different db table based on selection.  So far I have:

$("#table").change(function(){
    var tbll = $(this).val();
    if(tbl) {
             $('#grid').setGridParam({url: 'grid.php?table='+tbl});
             $('#grid').trigger('reloadGrid');
    }
});

This reloads the data but doesn't get new header/column from the new table column.  I read elsewhere that I should use GridUnload.  What is the method to rebuild the grid after a GridUnload?  I can't rebuild the grid once GridUnload is triggered.

Thank for any input in advance 🙂
