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");
9 N1 g6 f$ @; c( r/ z, m  treenode thesum = getvarnode(current,"targetcomponentsum");
  setnodenum(thesum,0);
3 l: A; N6 z( L; S* h
) B! ]  |! l6 Y% O# W4 p! W   {
  J! @9 c# N& x% E5 S     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
2 J9 r. Q: ]+ x8 C$ F    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"));
     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
6 s* N; ^8 W( p; k( s( D    inc(thesum,getlabelnum(first(current),"4"));
  }
- A8 ]" H; j; C' b) `1 n) Q. r}

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。
