Hi there!
I'm using org-mode to generate a table which has columns with mathematical expressions in certain columns.
#+caption: Berger's list of Holonomy groups
#+name: tab:holonomy
|---+---------------+-----------------------------+-----------------------|
| | Metric | Holonomy | Dimension |
|---+---------------+-----------------------------+-----------------------|
| / | <> | <> | <> |
| # | Kaehler | \( U(\tfrac{n}{2}) \) | \(n\in 2\mathbb{N} \) |
| # | Calabi-Yau | \( SU(\tfrac{n}{2}) \) | \(n\in 2\mathbb{N} \) |
| # | Hyper-Kaehler | \( Sp(\tfrac{n}{4}) \) | \(n\in 4\mathbb{N} \) |
| # | Quaternionic | \( Sp(\tfrac{n}{4})Sp(1) \) | \(n\in 4\mathbb{N} \) |
| # | Exceptional | \( G_2 \) | 7 |
| # | | \( Spin(7) \) | 8 |
