Description

When adding some image(s) in a table cell, no matter external file or code block, pandoc raises error and fails to output pdf.

$ pandoc markdown.md -t latex --filter=pantable -o pdf.pdf

pandoc: Error producing PDF

Tested if latex output differs by filtering: pantable generated source is not identical to inline table
- $ pandoc markdown.md -t latex --latex-engine=xelatex --filter=pantable -o latex.tex
- $ pandoc markdown.md -t latex --latex-engine=xelatex -o latex2.tex

$ diff latex.tex latex2.tex

From the diff the filtered latex contains \begin{figure}...\end{figure} block while inline does not. Can you confirm if this is a bug in pantable/panflute or pandoc itself?
