Exporting tables with cell borders to Latex/PDF

Exporting tables with cell borders to Latex/PDF

[jman]

Hello,

When export to Latex/PDF I'd like /all/ table cells to have borders, so also vertical column
separators.
After looking around a bit, I learned about column groups:
https://orgmode.org/manual/Column-Groups.html

I think the only way to accomplish what I want is the following trick, adding a "cosmetic" column
just to be able to have a border at the beginning of the table:

|---+---+-----+-----+-----+---------+------------|
|   | N | N^2 | N^3 | N^4 | sqrt(n) | sqrt[4](N) |
|---+---+-----+-----+-----+---------+------------|
| / | < |   < |   < |   < |       < |         <> |
|   | 1 |   1 |   1 |   1 |       1 |          1 |
|   | 2 |   4 |   8 |  16 |  1.4142 |     1.1892 |
|   | 3 |   9 |  27 |  81 |  1.7321 |     1.3161 |
|---+---+-----+-----+-----+---------+------------|
#+TBLFM: $2=$1^2::$3=$1^3::$4=$1^4::$5=sqrt($1)::$6=sqrt(sqrt(($1)))

Am I missing a better solution?

Thanks

Here is an example of using the #+ATTR_LaTeX: line to pass parameters to the LaTeX process that creates the pdf.

#+ATTR_LaTeX: :environment tabular :align |l|l|l|
|-----+-----+-------|
| one | two | three |
|-----+-----+-------|
|   1 |   2 |     3 |
|-----+-----+-------|

Oh thank you for the tip! Now I've found a mention in the documentation:
https://orgmode.org/manual/Tables-in-LaTeX-export.html

I'll try unpacking the solution for clarity: `l` means align to the left, the pipe (`|`) means add a 
vertical separator.
Here a bit more documentation about the tabular package:
https://www.overleaf.com/learn/latex/Tables

Note: I think it also works without setting `:environment tabular`, why?

Cheers,

The `:environment` attribute sets the LaTeX table environment, in this case tabular. If
you omit it, it uses `org-latex-default-table-enviroment', which defaults to "tabular", so
that wouldn't make a difference in this case.

Check out section "13.10.5 Tables in LaTeX export" of the Org manual:

    (info "(org) Tables in LaTeX export")

    ‘:environment’
         Set the default LaTeX table environment for the LaTeX export
         backend to use when exporting Org tables.  Common LaTeX table
         environments are provided by these packages: tabularx, longtable,
         array, tabu, and bmatrix.  [...]

For example, try this out:

#+ATTR_LATEX: :environment longtable :align |l|l|l|
|-----+-----+-------|
| one | two | three |
|-----+-----+-------|
|   1 |   2 |     3 |
|-----+-----+-------|
