今天遇到一个问题 一个数组

backingBestRoundTb = {

1 = {

"index" = 1

"shouShu" = 9

}

2 = {

"index" = 2

"shouShu" = 9

}

3 = {

"index" = 3

"shouShu" = 8

}

}

原来是这样 但是当我用

table.sort(backingBestRoundTb, function(a, b )

return a.shouShu < b.shouShu

end)

根据shouShu这个变量排序时 排序的结果成了

{

1 = {

"index" = 3

"shouShu" = 8

}

2 = {

"index" = 2

"shouShu" = 9

}

3 = {

"index" = 1

"shouShu" = 9

}

}

由此可见 table.sort并不是插入型排序 而是直接将 backingBestRoundTb[1]和 backingBestRoundTb[3]交换了位置 推测应该使用的是冒泡算法
