Inserting Elements

table.insert(t, [location],item,)

Insertion is done at the specified location by shifting any existing items towards the end and the table is resized.

Option	Description
t	The table on which to perform the operation.
item	The element to insert.
location (optional)	The location in the table at which to insert the element. By default, set to one plus the end of the table

You can append new elements at the end of a table array:

> t = {1,2,3}

> table.insert(t,21)

> print(Length(t))

> print(t[4]) // 4th entry

You can also insert elements at a chosen position in the table by providing the second argument location:

> table.insert(t,3,99)

> print(t[2], t[3], t[5]) // table size increased to 5
