Column width in tables

Hi pros,

Can I control column width of tables created in UI designer?

I am developing a table in UI for storing apartments inside Opportunities (alike standart Products are stored). The last column of this table is devoted to Actions. I need to fit there 5 buttons like this:

Unfortunatelly, every time I open the tab columns have equal width ini C4C inteface, so only 3 of the 5 buttons fit:

I tried using Screen adaptation to change column width, but it does not save the results.

Best regards,
