Graphics, Figures & Tables ⇒ Split Columns in a Table

[sw3quant]

I have a table which I construct as following (This is MWE):

Code: Select all

\documentclass[final,authoryear,3p,times]{elsarticle}

\begin{document}



\begin{sidewaystable}
\begin{center}
\captionof{table}{\bf my Table}
\footnotesize
\begin{tabular}{|C{0.6cm}|C{2.0cm}|C{2.0cm}|C{2.0cm}|C{2.0cm}|C{2.0cm}|C{2.0cm}|C{2.0cm}|}
  \hline
\textbf{Code}   & \head{Number of ohh (\# [\%])} &  \head{AHHH (P [\%])} &  \head{Mean WAAA (lots)} & \head{Number of PLOP (\# [\%])} &  \head{OHH Volume (G [\%])} & \head{Mean WAA (Y)} & \head{Fleeting Z (\%)} \\
  \hline \hline
  OR & X & X & X & X&  X & X  & X \\

  \hline
  Total & X [100.00] & X [100.00] & X & X [100.00] &  X & X & X \\
  \hline
\end{tabular}
\label{hi}
\end{center}
\end{sidewaystable}




\end{document} 

and it gives me a nice looking table, as per the attached pic. great.

However I now wish to split each col into two. I will use the first col as an example.

I wish the top row "Number of Ohh ()" to span two cols. Then a new row underneath that, which is 2 cells wide, with the names col A and colB.

Hence each existing col header cell is merged (in EXCEL language) and becomes the merged header for 2 new cols : col A and col B.

I have posted an attempt to show this.!

Having looked around on the web, I havent a clue how to do this. Can anyone help?

Thank you!

I guess you're looking for \multicolumn{<num of cols>}{<col specs>}{<cell contents>} that can be used to merge <num of cols> cells into one cell. Here is an example:

Code: Select all

\documentclass{article}
\usepackage{array}

\begin{document}

\begin{tabular}{|c|c|c|}
 \hline
  \multicolumn{2}{|c|}{Head 1} & Head 2 \\
 \hline
  a & b & c \\
 \hline
  a & b & c \\
 \hline
\end{tabular}

\end{document}
