Fix the WD Table column width and table width

Hi experts,

I have a table say ID:TABLE_1 which is already created, now problem we have text column say column1,

when you scroll the scroll bar the size of the table is varying due to the "data"in one of the  Colum. I need to fix the size of the column constantly depending on maxmum length of data.

Ex: column1

     Arun

     Arun Kumar

     Arun Kumar Wading

If this is in ABAP ALV we can fix it with below piece of code

1) we use    ws_layout-colwidth_optimize = 'X'.  In webdynpro table how can we do it?  

2) we can also use wa_fieldlayout-output length for Individual columns .In webdynpro table how can we do it?  

Thanks
