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");
8 s+ O4 Q0 W& E: ~+ d3 U  treenode thesum = getvarnode(current,"targetcomponentsum");
  setnodenum(thesum,0);

   {
: O* ^# J/ V4 o7 n2 i     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
    inc(thesum,getlabelnum(first(current),"1"));
- j2 L: m7 \- l  Z7 S     setnodenum(cellrowcolumn(thelist,2,1),getlabelnum(first(current),"2"));
- O/ q$ W) o, z    inc(thesum,getlabelnum(first(current),"2"));
     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));
    inc(thesum,getlabelnum(first(current),"3"));
0 u0 W4 ~3 C4 o/ L  g     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
    inc(thesum,getlabelnum(first(current),"4"));
2 q2 h( p2 f) @/ 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。
