Gents

Standard distance between borders of a double line separating columns (||) in a table is too wide.
How can I adjust the distance to make it narrow.

I need t oadjust both vertical and horizontal double lines in my table.

Thanks a lot for help !

This distance is given by the parameter \doublerulesep, which you can change using \setlength.
