Pandoc error with pander and pandoc 2.0

[muschellij2]

pandoc: PandocLuaException "[string \"local fig_caption = true...\"]:456: bad argument #2 to 'format' (number has no integer representation)"
Error: pandoc document conversion failed with error 1

Example Rmd where this occurs:

break_pandoc.zip

I have pander * 0.6.1 2017-08-06 CRAN (R 3.4.1) and I get the following error:

library(pander)

Are you sure it's a pander issue? Eg pander is generating some markdown failling pandoc? Checking the below:

It may not be a pander issue exactly, but using `knitr::kable` doesn't throw the error. Have you tried using `rmarkdown::render` and not `pandoc`? It may be the combination of the `render` and `pander` that's causing an issue. John

I have the same error trying to render the following markdown table:

"Code	Rendered math
$x$	$x$
$\theta$	$\theta$
$x_i^2$	$x_i^2$
$\frac{1}{n}\sum_{i=1}^n x_i$	$\frac{1}{n} \sum_{i=1}^n x_i$
$\frac{1}{n}\sum_{i=1}^n (x_i-\bar x)^2$	$\frac{1}{n} \sum_{i=1}^n \bar (x_i - x)^2$"

It seems to have to do with the length of the last cell in the last line, as if I shorten it, I don't get the error.
