Field catalog using cl_salv_table

Hi experts,

I am using cl_salv_table to display the data.

1.Is it possible to pass my own field catalog to this class as we pass for cl_gui_alv_grid.

We can get the functions by the following code....

  gr_funct = gr_table->get_functions( ).

   gr_funct->set_all( Abap_True ).

But,

2.How to hide specific functions and display few extra functions like 'FIND' etc..

3.How to set the column heading.

4.How to optimize the width of the column.

If I can pass my own field catalog to this I will be able to solve maximum issues.

Best Regards,

Eshwar
