Re: [Q] how to anticipate last iteration in for .. in pairs

[Kristofer Karlsson <kristofer.karlsson@...>]

for colnm, coltype in pairs(tb_columns) do
 -- do stuff with colnm and coltype
 
  if next(tb_columns, colnm) ~= nil then
    -- do stuff if this is the last iteration
  end
end

Hello,
what's a way to anticipate the last iteration
in loop over a table

for colnm, coltype in pairs(tb_columns) do


I understand that I can get the table length, and then
increment a counter, but for some reason I thought
the table length thing was not reliable at all the cases...
but cannot find a reference to it

is there a better way?


thank you
