【高级技巧】Lua有序插入：沙巴克贡献榜的即时落位

local function addScore(actor, name, sc)
    rows[#rows + 1] = {name = name, score = sc}
    table.sort(rows, function(a, b)
        return a.score > b.score end)   -- 每笔全表重排
end

local function addScore(actor, name, sc)
    local pos = #rows + 1
    for i = #rows, 1, -1 do
        if rows[i].score >= sc then
            pos = i + 1                 -- 找到落位
            break
        end
        pos = i
    end
    table.insert(rows, pos, {name = name, score = sc})
    sendmsg(actor, 1, "沙巴克贡献榜插入位 " .. pos)
end
