11 // This is the rewrite of the tabular (table) support.
13 // It will probably be a lot of work.
15 // One first goal could be to make the inset read the old table format
16 // and just output it again... no viewing at all.
18 // When making the internal structure of tabular support I really think
19 // that STL containers should be used. This will separate the container from
20 // the rest of the code, which is a good thing.
22 // Ideally the tabular support should do as the mathed and use
23 // LaTeX in the .lyx file too.
25 // Things to think of when desingning the new tabular support:
26 // - color support (colortbl, color)
27 // - decimal alignment (dcloumn)
28 // - custom lines (hhline)
34 // This is what I have written about tabular support in the LyX3-Tasks file:
36 // o rewrite of table code. Should probably be written as some
37 // kind of an inset. At least get the code out of the kernel.
38 // - colortbl -multirow
39 // - hhline -multicolumn
41 // o enhance longtable support
