# Latex Multirow Table formatting

I am trying to format a table using multirow and multicolumn. Most of it seems ok except that I am missing some borders and I would a line separator between row "Binary Classifier" and the row immediately beneath it (1 vs. 2) etc. I cannot seem to figure it out.

\begin{tabular}{|l|c|c|c|c|c|}
\hline
\multirow{2}{*}{Category} & \multicolumn{3}{c|}  {Binary Classifier} &  \multirow{2}{*}{Votes}    & \multirow{2}{*}{Result}\\

&  1 vs. 2  &  1 vs. 3   & 2 vs. 3\\
\hline Class 1 & Win & Win & X & 2 & Win \\
\hline Class 2 & X & X & Win & 1 & X \\
\hline Class 3 & X & X & X & 0 & X \\
\hline
\end{tabular}


• First, you will get quicker assistance with a compilable MWE. Search this site for MWE for more information. Second, change line 5 to read ' & 1 vs. 2 & 1 vs. 3 & 2 vs. 3& &\\ ' because in each row you must account for all specified columns (you declared there would be six) – R.

Just add a \cline for the missing horizontal line and add the missing cells for the second row.

Class 2 & X        & X        & Win      & 1 & X   \\\hline
Class 3 & X        & X        & X        & 0 & X   \\\hline

Save yourself some trouble while making it look more beautiful. Here are some general advice on printing tables.

• Don't use vertical lines, unless your table is meant to be read vertically.
• Use some different widths of horizontal lines. The booktabs-package has som nice predefined lengths(along with some very good advice), namely \toprule,\midrule and \bottomrule.
• Use a caption on top. (for figures, the caption can below it).
• Don't write \begin{tabular}{|l|c|c|c|c|c|} with that many repeating items. use \begin{tabular}{|l|*{5}{c|}} if you reall want vertical lines, or \begin{tabular}{l*{5}{c}} without vertical lines. That way, you specify the number of columns you want of type c, instead of typing one by one.
