textutils.tabulate is throwing an error upon use:
pcall: bad argument #2.1 (expected string, got number)

I simply tried running the old Computercraft wikis example:
http://www.computercraft.info/wiki/Textutils.pagedTabulate

a = {1,2,3}
b = {1,2,3}
textutils.tabulate(
    colors.orange, a,
    colors.lightBlue, b
)

textutils.pagedTabulate appears to have the same problem, switching tabulate with pagedTabulate yields the same result.
