# Assistance creating a table with different amount of columns on rows

I am trying to create a table in LaTex, which has different a number of columns on some rows, this is what I am trying to achieve:

           Title1             Title2
Row1   1    2     3       1     2    3

Row2

Row3


The only tables I have created previously have the dame amount of columns on each row, this one needs three columns on the top row and then 7 on the next three rows, just not sure how to achieve this.

\begin{tabular}{lcccccc} %say
&\multicolumn{3}{c}{Title1}&\multicolumn{3}{c}{Title2}\\
Row1 & 1&2&3&1&2&3\\
%and so on
\end{tabular}


Version with lines:

\begin{tabular}{|l|c|c|c|c|c|c|} %say
\hline
&\multicolumn{3}{c|}{Title1}&\multicolumn{3}{c|}{Title2}\\
\hline
Row1 & 1&2&3&1&2&3\\
%and so on
\end{tabular}

• How can I place grids around every item using this approach? – user28462 May 13 '13 at 23:16
• @user28462 The second version has got some lines. – Przemysław Scherwentke May 13 '13 at 23:20
• @user28462 Don't use vertical rules in your tables. Their quality will instantly improve. – egreg May 13 '13 at 23:20
• This will only supply vertical lines and not horizontal lines – user28462 May 13 '13 at 23:28
• @user28462 Vertical lines are from |, horizontal lines --- from \hline. If you need horizontal lines underlining only specific columns, you have \cline{col_begin-col_end}, e.g. \cline{2-4}. – Przemysław Scherwentke May 13 '13 at 23:32
