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