# Extra space on right hand side of table

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?

• Because you have asked for the table to fill \columnwidth but the contents are narrower than that. egreg's answer below provides a much simpler way to set your table. – Andrew Swann Oct 19 '14 at 10:37

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.

• The table is set up explicitly to occupy the full width of the textblock. Is the \centering instruction even needed? If anything, what's needed is \noindent. – Mico Oct 19 '14 at 10:41
• @Mico If the pseudocaption is wanted… – egreg Oct 19 '14 at 10:42
• Did you deliberately omit the pseudocaption? (The OP didn't have the pseudocaption inside the center environment -- can't tell if that was by design or not...) – Mico Oct 19 '14 at 10:43

You can have a simpler code using   tabularx. To improve the table, I use the S qualifier from the siunitx package for the Code columns, booktabs to have a better vertical spacing around horizontal rules and makecell for a common formatting of column heads. Also, it's better to have the Industry columns left-aligned, but that may be changed if you prefer centred columns.
