Lua - merge tables?

Question

I need to merge two tables, with the contents of the second overwriting contents in the first if a given item is in both. I looked but the standard libraries don\'t seem to

Answer 1

Here's what i came up with based on Doug Currie's answer:

function tableMerge(t1, t2)
    for k,v in pairs(t2) do
        if type(v) == "table" then
            if type(t1[k] or false) == "table" then
                tableMerge(t1[k] or {}, t2[k] or {})
            else
                t1[k] = v
            end
        else
            t1[k] = v
        end
    end
    return t1
end
