org-mode table/matrix in latex export

Question

I have an issue when exporting a table using *matrix environments. The align string appears in the cell content, whatever it is specified or not

#+CAPTION: my matrix
#+ATTR_LATEX: :mode displaymath :environment pmatrix 
| 1 | 2 | 3 |
| 4 | 5 | 6 |

#+CAPTION: my matrix
#+ATTR_LATEX: :mode displaymath :environment pmatrix :align ccc
| 1 | 2 | 3 |
| 4 | 5 | 6 |

Any idea about how to solve that?

Answer 1

Replace displaymath by math. So the header of your table should look like this:

#+ATTR_latex: :mode math :environment pmatrix :align ccc
