// This is the rewrite of the tabular (table) support.
// Ideally the tabular support should do as the mathed and use
// LaTeX in the .lyx file too.
// Things to think of when designing 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
