Table style that keeps column width

Is there a was to use also absolute widths instead of relatives?

For example i would like to have the 2 column tables set to relative 10/50 and all 3 column tables to absolut 5mm, 7mm and 9mm.

I like the way Nathans Script defines the widths at the end of the script - really easy to edit and useful.

Also i am looking for a way to use this script (with a dialog box) on the whole document or the actual selection or the actual table.

As far as I know, table styles do not specify column widths. It is easy to write scripts that create tables with specific column widths, but you might also consider the following technique:

1. Make a new paragraph style with tab stops at positions that correspond to the desired column widths.

2. Convert table to text, apply the above paragraph style, then convert text back to table. The columns should be where the tab stops were.

3. Apply the table style of your choice. Because table styles do not specify column widths, the columns keep the specified widths.
