16 // This is Juergen's rewrite of the tabular (table) support.
18 // Things to think of when designing the new tabular support:
19 // - color support (colortbl, color)
20 // - decimal alignment (dcloumn)
21 // - custom lines (hhline)
27 // This is what I have written about tabular support in the LyX3-Tasks file:
29 // o rewrite of table code. Should probably be written as some
30 // kind of an inset. [Done]
31 // o enhance longtable support
