Yes, but it may be slightly inconvenient:

Here is a helper function that creates an empty table where you can supply the parameters you want to create the table with:
function newtable(arraysize, hashsize)
    return loadstring("return {" .. ("nil,"):rep(arraysize) .. ("[0]=nil,"):rep(hashsize) .. "}")()

(If used in practice, it should probably have a cache for combinations of arraysize and hashsize)

The Lua bytecode does encode the two arguments to createtable in the
