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