Sometimes it is helpful to be able to provide partial border specifications, for either rows or columns.

•

\cline{i-j} provides a partial bottom border between columns i and j of the current row.
•

A combined use of \multicolumn and \multirow can build a partial vertical border.

Here is one illustrating example:

\begin{tabular}{cc|c|c|c|c|l}

\cline{3-6}

& & \multicolumn{4}{ c| }{Primes} \\ \cline{3-6}

& & 2 & 3 & 5 & 7 \\ \cline{1-6}

\multicolumn{1}{ |c }{\multirow{2}{*}{Powers} } &

\multicolumn{1}{ |c| }{504} & 3 & 2 & 0 & 1 & \\ \cline{2-6}

\multicolumn{1}{ |c }{} &

\multicolumn{1}{ |c| }{540} & 2 & 3 & 1 & 0 & \\ \cline{1-6}

\multicolumn{1}{ |c }{\multirow{2}{*}{Powers} } &

\multicolumn{1}{ |c| }{gcd} & 2 & 2 & 0 & 0 & min \\ \cline{2-6}

\multicolumn{1}{ |c }{} &

\multicolumn{1}{ |c| }{lcm} & 3 & 3 & 1 & 1 & max \\ \cline{1-6}

\end{tabular}
