It is Ctrl+I (hex 0x09).

In Lua you could do it like this:


tab = string.char (9)
print (tab .. "hello" .. tab .. "world")

If you are using Lua another approach is to look up string.format, and use fixed-width text fields.

For example:


print (string.format ("%-10s %-10s", "hello", "world"))

-->

hello      world

If you say %10s, then you have a string that takes at least 10 positions (more if it is wider), and the "-" makes it left-justified.

Of course, a simpler way in Lua is to use the \t character. For example:



print ("hi \t there")
