Maybe its just me and i dont see it from reading the module or what not, but i fail to see the advantange over just using an array of arrays, (and then dumping to a templater if nesscesary). So how is this better?

update
During further thought, maybe you should just write a module that would automagically generate a table from an array of arrays? Automatically doing nice things such as resizing everything to fit and so forth with colspans/rowspans, and then implementing the multiple outputs (xml n stuff)
