[置顶] lua进阶8-－ C++读取lua文件里的三维表

前面lua进阶里面讲到用C++读取2维表，但是最近又有了新的需求，lua文件里面出现了3维表，自己摸索了1下，终究找到了解决的方式，在这里面与大家分享1下</span>

stage = { {m_nId = 105,m_nBoss = 0,m_nScoreList = {300,450,600},m_nRewardList = {230401201,13020801,13010411},m_nDropItemList = {0,0}},{m_nId = 106,m_nScoreList = {630,840,1050},m_nRewardList = {241801101,14000201,18000201},m_nDropItemList = {14000101,241700301,230501301}},{m_nId = 107,m_nScoreList = {735,980,1225},m_nRewardList = {230400201,230400411,230500101},m_nDropItemList = {12020101,13010301,230401401}},{m_nId = 108,m_nScoreList = {840,1120,1400},m_nRewardList = {19000101,241500901,18040201},m_nDropItemList = {14000401,230401201,14000101}},{m_nId = 109,m_nScoreList = {1080,1440,1800},m_nRewardList = {12020301,230600101,241800501},m_nDropItemList = {16000401,230901101,230700301}},{m_nId = 110,m_nBoss = 1,m_nScoreList = {1200,1600,2000},m_nRewardList = {0,220200901},m_nDropItemList = {230902101,231101101,231000401}}
