variable tabulated-list-format

[John Haman]

Hi everyone,

I'm working on a mode that derives from tabulated-list-mode. My idea is 
to display small data.frames from ESS-R-mode using tabulated-list. As I 
may have several data.frames at a time, I need the header (column names) 
to vary with each call.

Looking at the docs for tabulated-list-mode 
(https://www.gnu.org/software/emacs/manual/html_node/elisp/Tabulated-List-Mode.html), 
it looks like usage requires that my derived-mode specify the column 
names and meta-data (tabulated-lis-format) in my definition of the 
derived mode.

Is there is way to do make `tabulated-list-format' variable? (that is, 
pass data to the macro define-derived-mode ?)
