I am trying to utilise all the whitespace in a two column (ieee) format document.
A set of tables must stay grouped on the same page, thus I've nested them under {table*}. Having done that, I now have some unutilised space marked in red as displayed in the image below.
Is there a way to adjust the height of the right hand side column to fill up the whitespace? Or, could you please suggest an alternative solution?
Thanks, Gin

\vspace*{-...}at the column break to bring up the start of the second column. – David Carlisle Mar 16 '16 at 23:40Werner, this is for a workshop. There aren't any guidelines apart from keeping the text within column margins.
I will try John's solution for now.
David, this will be my last resort as this solution is very sensitive to edits elsewhere.
