Multiline equation in a table

Question

Is there a way to make very long equation multiline so it doesn't stretch the table very long?

Answer 1

You can break the equation with the split environment:

\begin{equation}
  \begin{split}
    x &= a + b \\
    \quad + c + d \\
    &= x \cdot y \cdot z
  \end{split}
\end{equation}

Answer 2

Use a p{<length>} type column to wrap the cell contents into a paragraph. Or used aligned, etc., from amsmath to create a boxed multiline math expression.
