Description

Sort the elements of a table in-place (i.e. alter the table). > t = { 3,2,5,1,4 } > table.sort(t) > = table.concat(t, ", ") -- display sorted values 1, 2, 3, 4, 5

A comparison function can be provided to customise the element sorting. The comparison function must return a boolean value specifying whether the first argument should be before the second argument in the sequence. The default behaviour is for the < comparison to be made. For example, the following behaves the same as no function being supplied:

 table.sort(table,comp)

Parameters

table: (table) table to sort
comp: (function) comparison function returning bool comparison result optional
