how to add grid to table with pander?

I am working with R, knitr and pander, and I can't find the option that would allow me to print a grid on a table with pander. I tried :

pander(tableToPrint, style='grid')

but it doesn't do anything, neither with this option or with 'multiline', 'rmarkdown'... I always get an horizontal line, then the column names, another horizontal line, all my data and an horizontal line. I would like to have an horizontal line between every line. Another option would be to alternate row colors.

There is an old answer that gives the trick to do that in latex, but in needs a bit of adaptation to pandoc. One needs to add this to the latex code:

\catcode`@=11
\let \savecr \@tabularcr
\def\@tabularcr{\savecr\hline}
\catcode`@=12

However, it doesn't work if you add it through header-includes, probably because it is too late in the template. So the solution is to create a new template pandoc -D latex > template.tex (or use your usual template) and to add the previous code at the top, just after \documentclass. Then:

---
title: "Untitled"
output:
  pdf_document:
    keep_tex: yes
    template: "template.tex"
---

Produces lines at every row. The problem is, then, that the top and bottom line are doubled.

This is impossible for a docx output. Pandoc's docx template allow very little customization, and only of paragraph style.

For the sake of completeness, the html solution is even easier:

---
title: "Untitled"
output: html_document
---
<style>
th, td {
    border-bottom: 2px solid black;
}
</style>
