求高手帮小弟解释下以下代码！真心看不懂哇！！！
if isId(id) thendim arr
arr=array(0,0,0,0,0,0,0)
for i=0 to ubound(inArray,2)
response.write "<tr>"
response.write "<td noWrap>"&inArray(0,i)&" </td>"
response.write "<td noWrap>"&formatNum(inArray(1,i),2)&" </td>"
response.write "<td noWrap>"&formatNum(inArray(2,i),2)&" </td>"
response.write "<td noWrap>"&formatNum(inArray(3,i),2)&" </td>"
response.write "<td noWrap>"&formatNum(inArray(4,i),2)&" </td>"
response.write "<td noWrap>"&formatNum(inArray(5,i),2)&" </td>"
response.write "<td noWrap>"&formatNum(inArray(7,i),2)&" </td>"
response.write "<td noWrap> "&inArray(6,i)&" </td>"
response.write "</tr>"
arr(0)=arr(0)+Cdbl(inArray(1,i))
arr(1)=arr(1)+Cdbl(inArray(2,i))
arr(2)=arr(2)+Cdbl(inArray(3,i))
arr(3)=arr(3)+Cdbl(inArray(4,i))
arr(4)=arr(4)+Cdbl(inArray(5,i))
arr(5)=arr(5)+Cdbl(inArray(7,i))
next
response.write "<tr>"
response.write "<td noWrap>合计 </td>"
response.write "<td noWrap>"&formatNum(arr(0),2)&" </td>" '这个地方最需要注释了，实在搞不懂这合计怎么算的- -！
response.write "<td noWrap> </td>"
response.write "<td noWrap>"&formatNum(arr(2),2)&" </td>"
response.write "<td noWrap>"&formatNum(arr(3),2)&" </td>"
response.write "<td noWrap>"&formatNum(arr(4),2)&" </td>"
response.write "<td noWrap>"&formatNum(arr(5),2)&" </td>"
response.write " <td noWrap> </td>"
response.write "</tr>"
end if
