This question already has an answer here:

I want to span a cell across two rows using multicolumn. This works but the borders are missing then.


Why does multicolumn omit the borders and how do I get the borders?

    ...it's because you're overriding the column specification of the main tabular - |c|c| - with that of \multicolumn - c. The latter doesn't have any vertical rules in it. You should try \multicolumn{2}{c|}{..}. – Werner Jan 28 '16 at 15:22
