Question about table.maxn() and # operator

["Jon Nalley" <lists@...>]

I am having some difficulty understanding what is going on in the code below and was hoping someone could enlighten me.


t = { 'one', nil, 'three' }

print(#t) -- 3
print(table.maxn(t)) -- 3

table.insert(t, 5, 'four')

print(#t) -- 1
print(table.maxn(t)) -- 5


Why does #t change to 1 after the table.insert()?

If I specify a position < 5 to table.insert() then #t is not set to 1 and is the same as table.maxn(t).
