How to erase or reset a table in Lua

Question

How can I completely clear or flush a table in Lua. I want to do this in an empty table at the end.

Answer 1

You iterate over the keys and make them zero.

for k,v in pairs(t) do
  t[k] = nil
end

If it is an array, then delete the values ​​using table.remove ()

Answer 2

How about this way?

t = {..some non-empty table..}
...some code...
t={}

Answer 3

this will create a new table 't' with a new pointer and delete the old values:

t = {1, 2, 3}
t = {}
collectgarbage()

this element will delete all table values ​​and you will not get any table:

t = {1, 2, 3}
t = nil
collectgarbage()
