table.sort with Comparators

Sort tables with custom comparator functions and stable sort strategies.

What Is table.sort?

table.sort sorts a table in-place using a comparison function. Without a comparator it uses the < operator.

Call table.sort(t) on a table of numbers or strings to sort ascending.

local nums = {5, 2, 8, 1, 9}
table.sort(nums)
for _, v in ipairs(nums) do print(v) end
