Hi, The `:options' attr. allows adding an optional argument with various table options (between brackets in LaTeX export), since certain tabular environments, such as `longtblr' of the `tabularray' LaTeX package, provides this structure (see: https://list.orgmode.org/CALtzAB1yM+uG_xHghCxTLRX5mgbzNvT5+PO=DuaBB28nCsVqEA@mail.gmail.com/#r) Example: #+ATTR_LATEX: :environment longtblr #+ATTR_LATEX: :align colspec = {XXX}, width = 0.85\linewidth #+ATTR_LATEX: :options remark{Note} = {Lorem ipsum dolor sit amet} ==> \begin{longtblr}[remark{Note} = {Lorem ipsum dolor sit amet}]{colspec = {XXX}, width = 0.85\linewidth} Best regards, Juan Manuel
