I tried to use vtable.el to produce the syllable table.  There are two
problems:

    . all the calculation done by vtable is slow (perhaps to no one's
      surprise).
    . the buffer becomes noticeably slow to scroll after the table is
      inserted.

I've attached an elisp file of my current progress.

[table.el (application/emacs-lisp, attachment)]

When I commented out the make-vtable call and benchmarked it, it was
fast so it is not the creation of table data structure that is the
bottleneck.
