[Tex/LaTex] Hline and Cline in multirow/multicolumn environment

Question

Why when I using using multirow and multicolumn, my horizontal line does not appear?
This is my MWE:

\documentclass[parskip]{scrartcl}
\usepackage[margin=15mm]{geometry}

\usepackage{multirow}
\begin{document}
\begin{table}
\begin{tabular}{c|c|c|c|c|c|c}
\multirow{2}{*}{Iterasi} & \multicolumn{3}{c}{ Ketinggian rata-rata (\%)}& \multicolumn{3}{c}{Luas Sebaran (\%)} \\ 
\cline{2-6}
\end{tabular}
\caption{Test}
\label{tabel  stiffness}
\end{table}
\end{document}

Answer 1

When using \multicolumn you cannot stop a \cline at a column that is 'inside' of the \multicolumn, so changing \cline{2-6} to be \cline{2-7} in your code works.

Also, if you want to use \multirow, you actually need to include another row, otherwise you won't get "Iterasi" to be in two rows.

\documentclass[parskip]{scrartcl}
\usepackage[margin=15mm]{geometry}

\usepackage{multirow}
\begin{document}
\begin{table}
\begin{tabular}{c|c|c|c|c|c|c}
\multirow{2}{*}{Iterasi} & \multicolumn{3}{c}{Ketinggian rata-rata (\%)}& \multicolumn{3}{c}{Luas Sebaran (\%)} \\ \cline{2-7}
\\
\end{tabular}
\caption{Test}
\label{tabel  stiffness}
\end{table}
\end{document}
