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");
  treenode thesum = getvarnode(current,"targetcomponentsum");
- W% O4 h# f' `% x. `8 T) _& M  setnodenum(thesum,0);

/ U5 N- [8 u$ S$ _. L6 r, K' c   {
     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
! A' U  y7 A! B    inc(thesum,getlabelnum(first(current),"1"));
0 d$ C4 n" R+ Y# o) E4 x     setnodenum(cellrowcolumn(thelist,2,1),getlabelnum(first(current),"2"));
    inc(thesum,getlabelnum(first(current),"2"));
, @8 ?5 {8 I4 ^6 W7 b     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));
* M  o6 N7 \/ f+ b* q9 o    inc(thesum,getlabelnum(first(current),"3"));
4 _& L( {4 X' B+ N# A4 l5 ^     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
& }+ t+ I% ~) K. m6 k    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。
