How to make table object has the shortcut ability as string

[Tang Daogang <daogangtang@...>]

Dear all,

I have a table

a = { '1', '2', '3' },

now, I can use

table.remove(a, 2)

to remove the second element. But I want to write

a:remove(2)

to achieve the same result, just like string's ability. Is there some way to implement it?

Maybe there are already discussions on it in this list before, but I don't know what key word to use to search, so ask here for help.

Thx.
