table.insert
Lua function table.insert Summary Inserts a new item into a numerically-keyed table Prototype `table.insert (t, pos, value)` Description `Inserts the value at (optional) position 'pos', renumbering existing elements if necessary to make room. Thus the new element becomes the one with index 'pos'. If called with 2 arguments, the value is inserted at n+1, that is, the end of the table.
    t = { "the", "quick", "brown", "fox" }
    table.insert (t, 2, "very") -- new element 2
    table.insert (t, "jumped")  -- add to end of table
    table.foreachi (t, print)

     -->

    1 the
    2 very
    3 quick
    4 brown
    5 fox
    6 jumped
The Lua authors recommend using the idiom "#t + 1" to insert to the end of a table nowadays. For example:
    t = {}
    t [#t + 1] = "hello, "
    t [#t + 1] = "world"
Note that for other keys (eg. strings) you simply assign to the table item to insert it. For example:
    t = {}
    t.foo = "bar"    -- insert key "foo"
    t ["Nick Gammon"] = 42  -- insert key "Nick Gammon"
