  • Welcome to TeX.SX! In the first row you're asking for 3+4+8+3+4+2+3+3=30 columns, that you don't have. Shouldn't be there a \\ after “Daily Problems”? Also the following & should be removed.

  • I inserted the table entered in Excel.

You forgot to end the first row:

\begin{tabular}{|ccc||cccc||cccccccc|}
\multicolumn{3}{c}{\textbf{Instances}}
&\multicolumn{4}{c}{\textbf{Weekly Problem}}
&\multicolumn{8}{c}{\textbf{Daily Problem}}\\ % end of first row
\multicolumn{3}{c}{}
&\multicolumn{4}{c}{\underline{Heuristic (WPA)}}
&\multicolumn{2}{c}{} &
\multicolumn{3}{c}{\underline{Heuristic (DPA)}} &
\multicolumn{3}{c}{\underline{Large Neighborhood Search (LNS)}}\\
