Question

I have tried to create tables with latex and I've failed and it happens in forums like here

Answer 1

\begin{tabular}{ l c r }
1 & 2 & 3 \\
4 & 5 & 6 \\
7 & 8 & 9 \\
\end{tabular}

Answer 2

\begin{tabular}{ |l|l| }
\hline
\multicolumn{2}{|c|}{Team sheet} \\
\hline
GK & Paul Robinson \\
LB & Lucus Radebe \\
DC & Michael Duberry \\
DC & Dominic Matteo \\
RB & Dider Domi \\
MC & David Batty \\
MC & Eirik Bakke \\
MC & Jody Morris \\
FW & Jamie McMaster \\
ST & Alan Smith \\
ST & Mark Viduka \\
\hline
\end{tabular}

Answer 3

\[\begin{array}{ l c r }
1 & 2 & 3 \\
4 & 5 & 6 \\
7 & 8 & 9 \\
\end{array}\]I would suggest using "array" instead of "tabular."

Answer 4

The MathJax is limited in what modules it supports. The good news is, many of the formatting tools will work in array for changing justification and adding lines.

\[\begin{array}{|rc|l|}
\hline1 & 820 & 3\\
\hline740 & 5 & 960\\
\hline
\end{array}\]

Also, if you really need a little more range of things, you could use this:

Then you can link it:

Which may be ugly at times, so you could also download it as a gif/png (change background to white!) and then save than and attach it.
