如何将PB的交叉报表转换成EXCEL形式(包括标题和合计的完整形式)
函数部分：（还用到了PFC的字串处理的一个函数和在本对象中的一个取值函数）
//====================================================================
// [PUBLIC] Function uf_data2excel 在 u_data2word inherited from nonvisualobject
//--------------------------------------------------------------------
// 说明:将数据倒入excel中,支持计算列及显示格式,要求在题头的计算列要写tag值
//--------------------------------------------------------------------
// 参数1:[value] datawindow adw
// 说明:数据窗口
//--------------------------------------------------------------------
// 返回: (INTEGER) 成功返回1,不成功返回0

//变更日志：020515加入对交叉表倒出的支持(主要是修改了保存题头部分)

PFC的字串处理函数（可直接改成全局函数就可用了）
//====================================================================
// [PUBLIC] Function of_lastpos 在 n_cst_string inherited from n_ccu_base
//--------------------------------------------------------------------
// 说明:找出一字串在另一串中最后出现的位置
//--------------------------------------------------------------------
// 参数1:[value] string as_source
// 说明:源串
// 参数2:[value] string as_target
// 说明:目标串
// 参数3:[value] long al_start
// 说明:开始位置
//--------------------------------------------------------------------
// 返回: (LONG) 从右数起出现的位置，找不到则返回0
//--------------------------------------------------------------------
Long ll_Cnt, ll_Pos
//Check for Null Parameters.
IF IsNull(as_source) or IsNull(as_target) or IsNull(al_start) Then
SetNull(ll_Cnt)
Return ll_Cnt
End If
//Check for an empty string
If Len(as_Source) = 0 Then
Return 0
End If
// Check for the starting position, 0 means start at the end.
If al_start=0 Then
al_start=Len(as_Source)
End If
//Perform find
For ll_Cnt = al_start to 1 Step -1

得到一个数据窗口列及计算列的准确显示值函数：
//====================================================================
// [PUBLIC] Function uf_getdata 在 u_data2word inherited from nonvisualobject
//--------------------------------------------------------------------
// 说明:得到一个数据窗口列及计算列的准确显示值
//--------------------------------------------------------------------
// 参数1:[value] datawindow dw_1
// 说明:
// 参数2:[value] string col
// 说明:对象名
// 参数3:[value] integer row
// 说明:行
//--------------------------------------------------------------------
// 返回: (STRING) 值
//--------------------------------------------------------------------
// 作者: cwl 日期: 2002.03.18
//====================================================================
string ls_edittype,ls_value,ls_format
integer id
ls_edittype=lower(dw_1.Describe(col+".Edit.Style"))//得到编缉风格
choose case ls_edittype
case 'ddlb','dddw'//应该得到显示值
ls_value=dw_1.describe( "Evaluate('LookUpDisplay("+col+") ',"+string(row)+" )")
case else
id=long(dw_1.Describe(col+".id"))
ls_format=dw_1.Describe(col+".Format")
if mid(ls_format,1,1)='[' or ls_format='?' or ls_format='' then //不作格式处理
if id=0 then //计算列
ls_value=dw_1.Describe("Evaluate(~"" + dw_1.Describe(col + '.expression')&
+ "~","+string(row)+")")
else
ls_value=string(dw_1.object.data[row,id])
end if
else
if id=0 then //计算列
ls_value=string(dw_1.Describe("Evaluate('" + dw_1.Describe(col + '.expression')&
+ "',"+string(row)+")"),ls_format)
else
ls_value=string(dw_1.object.data[row,id],ls_format)
end if
end if
end choose
if isnull(ls_value) then ls_value=''
return ls_value
--------------------------
最简单的解决办法,把dw存成html文件,然后改扩展名为.xls,一切ok了
