Description

I have problem with tables generated that contains %.

When I manually convert numbers to strings, and add % sign at the end of it - table is generated properly in html, docx and pdf (trough TinyTeX).

When trying to format numerical column with fmt_number(pattern = "{x}%") table is generated in html and docx but breaks in pdf.

Reproducible example

Code:

accuracy <- data.frame(HNK = 105.11, KET = 101.11, NKT = 96.14, DHNK = 96.69)

gt(accuracy) |>
  fmt_number(pattern = "{x}%")

generates LaTeX code:

\begin{longtable*}{rrrr}
\toprule
HNK & KET & NKT & DHNK \\ 
\midrule\addlinespace[2.5pt]
$105.11$% & $101.11$% & $96.14$% & $96.69$% \\ 
\bottomrule
\end{longtable*}

This code gives error mesage:

compilation failed- error
Misplaced \noalign.
\bottomrule ->\noalign 
                       {\ifnum 0=`}\fi \@aboverulesep =\aboverulesep \global...
l.252 \bottomrule

When I manually add % sign to numbers it is like follows:

accuracy2 <- data.frame(HNK = "105.11%", KET = "101.11%", NKT = "96.14%", 
    DHNK = "96.69%")

gt(accuracy2)

to LaTeX:

\begin{longtable*}{rrrr}
\toprule
HNK & KET & NKT & DHNK \\ 
\midrule\addlinespace[2.5pt]
105.11\% & 101.11\% & 96.14\% & 96.69\% \\ 
\bottomrule
\end{longtable*}

This table is converted properly to pdf

Expected result

After manual edit of .tex file generated by quarto (after fmt_number) to look like this:

\begin{longtable*}{rrrr}
\toprule
HNK & KET & NKT & DHNK \\ 
\midrule\addlinespace[2.5pt]
$105.11$\% & $101.11$\% & $96.14$\% & $96.69$\% \\ 
\bottomrule
\end{longtable*}

TeXstudio generates proper pdf from it.
