求教！哪位大神给我讲解一下这一串代码是什么意思？新手上路，很着急！！！！！！！

treenode thelist = getvarnode(current,"componentlist");
- [8 v9 e' [/ Q  treenode thesum = getvarnode(current,"targetcomponentsum");
3 w+ y1 p1 M, l; r  setnodenum(thesum,0);
3 J* s/ [1 ?# x! a- ]/ e
   {
     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
7 ~7 A- v9 T; C( _9 o    inc(thesum,getlabelnum(first(current),"1"));
     setnodenum(cellrowcolumn(thelist,2,1),getlabelnum(first(current),"2"));
    inc(thesum,getlabelnum(first(current),"2"));
     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));
    inc(thesum,getlabelnum(first(current),"3"));
, J4 C* t1 ^0 m- R* o/ f0 ~& b! n     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
    inc(thesum,getlabelnum(first(current),"4"));
  }
}

你的代码不全啊，但是大概就是根据当前实体的标签值设置属性节点“componentlist”（好像是个表格）的值，，然后将节点targetcomponentsum的值加対应标签的值。
