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");
/ I: m% M9 L/ V- c& s  setnodenum(thesum,0);
4 j5 E6 H1 G0 T2 o; {
% G* c" e8 ]5 ^( |% l# \   {
+ W7 r2 U: V. _     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
    inc(thesum,getlabelnum(first(current),"1"));
     setnodenum(cellrowcolumn(thelist,2,1),getlabelnum(first(current),"2"));
: a1 C# q5 P3 N; ^8 b+ t    inc(thesum,getlabelnum(first(current),"2"));
     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));
$ t8 j! K( [# q    inc(thesum,getlabelnum(first(current),"3"));
$ g* O2 m3 j  F1 g7 W* \     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
    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。
