Concatenation of tables in Lua

Question

ORIGINAL POST

Given that there is no built in function in Lua, I am in search of a function that allows me to append tables together. I have googled quite a bit and have tried every solutions I stumbled across but none seem to work properly.

The scenario goes like this: I am using Lua embeded in an application. An internal command of the application returns a list of values in the form of a table.

What I am trying to do is call that command recursively in a loop and append the returned values, again in the form of a table, to the table from previous iterations.

EDIT

For those who come across this post in the future, please note what @gimf posted. Since Tables in Lua are as much like arrays than anything else (even in a list context), there is no real correct way to append one table to another. The closest concept is merging of tables. Please see the post, "Lua - merge tables?" for help in that regard.

Answer 1

Overcomplicated answers much?

Here is my implementation:

function TableConcat(t1,t2)     for i=1,#t2 do         t1[#t1+1] = t2[i]     end     return t1 end
