# Equation Array Nested inside Tabular

This kind of set up where equation array or some align environment, doesn't seem to work inside tabular environment event if math mode is enabled:

Eg : Align

\begin{align*}
(1+x)^2 &= 2\\
\frac{3}{4} &=\frac{x}{(1+y)}\\
\end{align*}


Eg : Tabular

\begin{tabular}
\alpha &\gamma\\
\beta &\delta
\end{tabular}


Eg : Nesting Align inside Tabular - doesn't work

Nested
Tabular {
Align
}
\newcommand{\test}{\begin{align*}
(1+x)^2 &= 2\\
\frac{3}{4} &=\frac{x}{(1+y)}\\
\end{align*}}

\begin{tabular}
\alpha &\gamma\\
\beta &$\test$
\end{tabular}


SOLUTION : Change align* to aligned environment.

• You can't encase an align* environment inside a tabular environment. Use an aligned environment instead. – Mico Apr 24 '16 at 18:34
• Incidentally, your tabular declarations have no chance of being compilable. – Mico Apr 24 '16 at 18:39

• tabular is in "text" mode. You need to change cells in "math" by use of $...$.
• tabular should have defined column types, for example \begin{tabular}{cc}
• including multiline equations is tricky. For example, instead \begin{align*} ... end{align} you should write something like \begin{aligned} ...\end{aligned} from amsmath package.
For some concrete solution, prepare (not)working minimal example starting with \documentclass{...} necessary packages and encapsulate your code between \begin{document} and \end{document}.
• The aligned environment is actually provided by the amsmath package. – Mico Apr 24 '16 at 19:01
• Yes, i messed with multlined. Sorry for wrong information, I will correct this. – Zarko Apr 24 '16 at 19:55
