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