Any way to output latex table in a two-column document?

[yl4070]

Currently, the latex output depends on the longtable package, if it's used in a two column format, although it can still render the table, will result in an error: longtable is not used in one-column format.

Is there any option to not use longtable package or any workaround to avoid the latex error while keeping the two column format (not temporally switch to one column format)?

It is extremely hacky, but I worked around longtable like so:

cat(gsub("longtable", "tabular", gt::as_latex(gt_table)))

It really would be nice if as_latex() were more customizable.

In the dev version of gt, we output as tabular by default

I've had the issue with tables not being able to span over two columns as well. @olivroy I think I have a fairly simple solution for this for floating tables by setting begin{table} and end{table} to begin{table*} and end{table*}. Adding an argument to tab_options() such as latex.span_multicols = TRUE which would add the asterisk and only apply if latex.use_longtable = FALSE. Would this be of interest?
