how to add the cross vertical line in two column table. There should be cross vertical line in below. My code is starting like this:
\begin{table*}[t]
\centering
\caption{cap}
\scalebox{0.67}{
\begin{tabular}{c|ccc|ccc|ccc}
\toprule
kk & 1 & 2 & 3 & 1 & 2 & 3 & 1 & 2 & 3 \\
\midrule
name & \multicolumn{3}{c}{aa} & \multicolumn{3}{c}{bb} & \multicolumn{3}{c}{cc} \\


booktabsdo not cooperate well with vertical lines. So either remove the vertical lines (as suggestet in thebooktabsmanual) or use different horizontal lines. Vertical table lines are discontinuous with booktabs might be interested. – leandriis Mar 11 '19 at 15:22\scaleboxwith tables it will produce inconsistent font sizes and rule widths, – David Carlisle Mar 11 '19 at 15:44
