Usage

local p = {}

local function isnotempty(s)
	return s and s:match( '^%s*(.-)%s*$' ) ~= ''
end
 
function p.table(frame)
	local args = (frame.args[1] ~= nil) and frame.args or frame:getParent().args
	local cols
	if isnotempty(args['4thcoltitle']) and isnotempty(args['3rdcoltitle']) then
		cols = 4
	elseif isnotempty(args['3rdcoltitle']) then cols = 3
	else cols = 2
	end

	-- compute the maximum cell index
	local cellcount = 0
	for k, v in pairs( args ) do
		if type( k ) == 'number' and isnotempty(v) then
			cellcount = math.max(cellcount, k)

	end
	-- compute the number of rows
	local rows = math.ceil(cellcount / cols)

	-- create the root table
	local root = mw.html.create('table')

	-- add the header row
