regex

If I want to get the length of each match within the parentheses in the following regex, how do I do it?:

^\(\-\+\s\)\+

I'm trying to modify the width of columns in a buffer with data that is laid out as a table. Since the first two rows of the table will look like this

 DESIGN_ID DESIGN_YEAR SOURCE_REFERENCE
---------- ----------- ----------------

I want to use the regular expression to find the current width of each column.
