I have a table that represents a timetable for bus, so each cell contains time of departure as hour followed by minute, both as two digits, but sometimes I don't have two digits,just one so I have to switch eg. from 12 4 -> 12 04.
How is it possible?

This is a little workaround to get what you need:
\documentclass[12pt,letterpaper]{article}
\usepackage{amsmath}
\begin{document}
\begin{tabular}{p{8cm}p{8cm}}
{\begin{align}
&\alpha = \beta + \gamma \\
&c = 20x^2 + 5x - 10
\end{align}}
&
{\begin{align}
&x_f = x_0 + v_0t \\
&\mu = 10 * \epsilon
\end{align} }
\end{tabular}
\end{document}
The key concepts with this example are:
- You use tabular with columns defined by
p{dim}. - The tabular has only one row.
- For every cell of the tabular, you have an array of equations (
align), whose equations are defined at the right of the&, so they get aligned to the left. - Very important trick: to compile, you have to enclose every
alignenvironment inside{}, so that the&doesn't collide with those of thetabular.
One flaw this approach has: as every align environment is independent from the others, if one of the equations has more height, then they will look misaligned vertically. Try writing the
\frac{at^2}{2}
to the right of the third equation.
Using the eqnarray environment instead of array, you can add \nonumber to any lines you don't want numbered. If you don't do this, every line will be numbered.
\begin{eqnarray}
N_{x,sk} &=& k_{sk}\left(\frac{t_{sk}}{b_{sk}}\right)^{2}\bar{Et} \nonumber \\
N_{x,st} &=& k_{st}\left(\frac{t_{st}}{b_{st}}\right)^{2}\bar{Et}
\end{eqnarray}
(Just remove the \nonumber from the above to get the second example.)

You can define a macro as follows:
This macro is fully expandable.
If you also want to cut trailing zeros you can use:
If you want to change a
tabularcell from12 4to12 04without adding explicit macros you can use thecollcellpackage to collect the cell content and feed it to a macro which splits the numbers by the space:If you post a real usage example I can help me with more specific macros.
