how to add SORT tab in the SETTING for any tables

Dear All,

I am working on Web Dynpro ABAP and configure the page with 2 list(tables). As per the requiremt these table should have sorting (column wise) functionality.

For one table it is working fine as I have done the required settngs on SORT tab of SETTING for this perticuler table. My problem is that for the another table this SORT tab is not coming, if i check in the SETTING of this table.

Please advise how I can add SORT tab in the SETTING for any tables.

Thanks & Regards,
