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");
+ T: b' K& j( g8 u5 F$ @) I  treenode thesum = getvarnode(current,"targetcomponentsum");
  setnodenum(thesum,0);

   {
     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
    inc(thesum,getlabelnum(first(current),"1"));
     setnodenum(cellrowcolumn(thelist,2,1),getlabelnum(first(current),"2"));
6 M; S' X4 O$ N9 |. i% ?% }1 e    inc(thesum,getlabelnum(first(current),"2"));
) X4 a7 o: I/ x8 }! t     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));
* T% v3 @$ N1 W9 @3 _7 ^    inc(thesum,getlabelnum(first(current),"3"));
     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
7 V/ u! V& W  H! l$ Y$ r    inc(thesum,getlabelnum(first(current),"4"));
- h- `5 V# q8 c: M5 B  }
+ U8 F5 \1 j" s) O}

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。
