I am trying to make the transition for Data Tables from PG to PGML.
I understand that while in PG I must write:
\{
DataTable( table contents...);
\}
While in PGML this must be changed to:
[@
DataTable( table contents...);
@]*
However it seems that by doing so that I have lost some formatting options within the Data Table. For instance bold type, and line breaks wont display using either PG or PGML syntax.
Is there a different syntax for bold type and line breaks within data table cells that are built in PGML?
I have attached an example that shows two identical data tables. The first is in PGML the second is in PG. How can I give the same formatting in the PGML table. Thanks for the help!
