Cannot use multiple tab_source_note in a LaTeX table (works in HTML)

[vincentarelbundock]

We can use multiple calls to tab_source_note to insert multiple notes at the bottom of a table. These notes appear correctly in HTML, but only the first note appears in LaTeX output.

Example:

library(gt)

tab <- data.frame(x = 1:2, y = 2:3) %>%
       gt %>%
       tab_source_note('note 1') %>%
       tab_source_note('note 2')

tab %>% as_latex %>% cat
#> \captionsetup[table]{labelformat=empty,skip=1pt}
#> \begin{longtable}{cc}
#> \toprule
#> x & y \\ 
#> \midrule
#> 1 & 2 \\ 
#> 2 & 3 \\ 
#> \bottomrule
#> \end{longtable}
#> \begin{minipage}{\linewidth}
#> note 1\\ 
#> \end{minipage}

The result is correct in HTML:

The problem is related to Line 326 of the utils_render_latex.R file, which only selects the first element of the list of notes. In my gt fork, I removed that line and it fixed the problem:
