[Tex/LaTex] Extra space on right hand side of table

landscapetables

I have a table in landscape mode, and there is extra space on the right-hand side of my table (see yellow circle). What changes need to be made so that the text is spread evenly across the table?

Best Answer

Your input is way too complicated. The problem is that you never let LaTeX add the extracolsep, because you're always overriding the template with \multicolumn.
