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");
1 ~2 v  `  N4 r- i  setnodenum(thesum,0);
7 G1 V1 P6 A3 X* I  I' K$ c9 G
   {
" U0 p$ Y; x, e* r, T5 B     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
    inc(thesum,getlabelnum(first(current),"1"));
     setnodenum(cellrowcolumn(thelist,2,1),getlabelnum(first(current),"2"));
1 ]0 ^' q( T. I0 n! v9 L7 K    inc(thesum,getlabelnum(first(current),"2"));
     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));
* i! x  P! S6 F9 }    inc(thesum,getlabelnum(first(current),"3"));
. H7 V* e' }1 A" ~6 D) b; V8 [     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
    inc(thesum,getlabelnum(first(current),"4"));
# N- n6 r7 n5 a5 W8 F& o  }
; q  b+ f, ~" J7 F' I4 c}

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。
