# [xwiki-devs] [Brainstorming] LaTeX Renderer - Styling

Hi devs,

I’m currently working on improving our TeX renderer (which is really a POC
ATM), in an effort to see if it could be used to generate nice PDF exports (you
generate LaTeX and then you convert to PDF).

The main issue is that LaTeX doesn’t have any technology for applying style to
it (like CSS has for HTML). In addition I wasn’t able to find any good HTML+CSS
to TeX converter (as we have for PDFs with XSLT+FOP).

So right now my idea is to implement some default behavior in the Tex Renderer
(that could be configured globally in xwiki.properties and/or in the Admin UI)
and give the ability to override specifically in the content.

For example, imagine that you need to decide how to position table column
content (left, centered, right) or whether the rows and/or columns of your
table have vertical and horizontal lines (or other configs, autowrap, etc).

The idea is that the Tex Renderer would support some custom tex-specific
parameters. For example:

(% tex-table-spec=“c | c | c" tex-table-floating="true"
tex-table-caption="caption" %)
|=A|=B
(% tex-table-row-ending="\hline" %)|a|b

(by default the table spec would be left aligned with vertical lines, and rows
would be separated by horizontal lines).
