WoWInterface - Code to Convert a Table to a List (for lack of better terms)

So here is my situation for my addon. Here is a function very similar to one I have:

Code:

function testFunction(parent, index, ...)

        return tableOfFunctions[index](parent, ...)

end

A call to this function would look like:

Code:

local i = object:testFunction(index, param1, param2, param3)

however the function can be called with anywhere from 1 parameter (just the index) to 6 parameters (index + 5 other parameters). This all works just fine but what I want to do is to be able to call the function like this:

Code:

local paramTable = {index, param1, ...}

local i = object:testFunction(paramTable)

Essentially I am passing just one parameter (a table) and I need some code to put into testFunction() that will then split up that table into individual parameters and pass the correct ones onto tableOfFunctions[index](...).

Is there any better way of doing this than to just get the length of the table and then have an if statement for every number of parameters like this?:

Code:

function testFunction(pTable)

        local length = #(pTable)

        if length == 2 then

                tableOfFunction[pTable[2]](pTable[1])

        elseif length == 3 then

                tableOfFunction[pTable[2]](pTable[1], pTable[3])

        elseif length == 4 then

                tableOfFunction[pTable[2]](pTable[1], pTable[3], pTable[4])

        elseif length == 5 then

                tableOfFunction[pTable[2]](pTable[1], pTable[3], pTable[4], pTable[5])

        elseif length == 6 then

                tableOfFunction[pTable[2]](pTable[1], pTable[3], pTable[4], pTable[5], pTable[6])

        elseif length == 7 then

                tableOfFunction[pTable[2]](pTable[1], pTable[3], pTable[4], pTable[5], pTable[6], pTable[7])

        end

end

I realize that that solution would work just fine but I am still curious if there is a better way of doing it as I enjoy learning new programming tricks :).

Thanks
