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