lua学习笔记15：table数组逆序

数组的逆序，只能用于数组，不能用于哈希表

function reverseTable(tab)local tmp = {}for i = 1, #tab dolocal key = #tabtmp[i] = table.remove(tab)endreturn tmpend// 示例local t = {"one", "two", "three"}for k, v in pairs(t) doprint(k, v)endt = reverseTable(t)for k, v in pairs(t) doprint(k, v)end

输出：

1 one
2 two
3 three
1 three
2 two
3 one
