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");
- A8 L  |' H9 i9 x) j  treenode thesum = getvarnode(current,"targetcomponentsum");
  Q6 t" ~( v* [! X  setnodenum(thesum,0);

4 }% J+ k/ D, o3 o/ ]/ ?   {
8 X7 P2 Z/ B& z% S     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
    inc(thesum,getlabelnum(first(current),"1"));
* f3 n$ i4 o1 C1 B( I     setnodenum(cellrowcolumn(thelist,2,1),getlabelnum(first(current),"2"));
3 `3 m) {1 Z+ Z6 m# \    inc(thesum,getlabelnum(first(current),"2"));
; @' T# l3 v6 ]/ d8 E) ?     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));
    inc(thesum,getlabelnum(first(current),"3"));
     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
    inc(thesum,getlabelnum(first(current),"4"));
: x1 |' [& V7 P! i7 G  }; l  W  }
' R2 u, A* z, [# j5 ^}

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。
