网上的教程说的太模糊，在下才疏学浅，反复尝试不得要领，还请各位大侠详细分说，多谢！
如这段：
new treasuretable "Luck7"
new subtable "0,55;1,5;2,24;3,16"
object category "T_ST_RandomLootSuper",20,0,0,0,0,0,0,0
object category "T_ST_Skillbook",10,0,0,0,0,0,0,0
object category "T_ST_RareIngredient",5,0,0,0,0,0,0,0
object category "T_ST_WeaponRare",27,0,0,0,0,0,0,0
object category "T_ST_ArmorRare",9,0,0,0,0,0,0,0
object category "T_ST_RingAmuletBeltRare",3,0,0,0,0,0,0,0
object category "T_ST_WeaponLegendary",24,0,0,0,0,0,0,0
object category "T_ST_ArmorLegendary",12,0,0,0,0,0,0,0
object category "T_ST_RingAmuletBeltLegendary",7,0,0,0,0,0,0,0

红色部分是何意义？另外
new treasuretable "LuckTop"
lucktop什么意思？
