Reply To: Edit multiple tables in Indesign 5?

Don’t think so – table styles don’t offer you column widths.
You can reduce the pain a little by making the standard widths nice round numbers, then selecting column by column and typing those numbers in the column width box that appears either in the Table palette or in the top toolbar.

It is possible to paste all the rows of one table into another table which already has the correct column widths (i.e. a template), but if yours are linked to a content management system, that doesn’t sound like an option.
