如何把cxGrid数据导出到EXCEL文档

怎么把cxGrid数据导出到EXCEL文档?
各位大虾，本人初次接触BCB，碰到了一个问题，请教各位：我的界面上有五个cxgrid网格，现在我要一次性把他们的数据全部导出到EXCLE里面去，我能导出一个，但是要连续导其他的话，最后EXCLE里面的数据就只有最后一个数据表的数据了。怎么办啊？很急得要，HELPING。。。。。。。。。。。。。。。。。

// 你参考一下，这是一个数据表导至 Excel 的函数

void __fastcall ADOQuery2Excel (TADOQuery* ADOQuery, String elxFilename, bool CloseExcel)

try

}
catch (...)
{
try
{
my_excel = Variant::CreateObject( "excel.application ");
}
catch (...)
{
ShowMessage( "GetExcel failed. ");
return;
}
}
my_excel.OlePropertySet( "Visible ",(Variant)true);

// ----------------------------

Variantall_workbooks;
Variantmy_workbook1;

//-- Get workbooks collection
all_workbooks= my_excel.OlePropertyGet( "Workbooks ");

//-- Set number of worksheets to 1
my_excel.OlePropertySet( "SheetsInNewWorkbook ",(Variant)1);

//-- Create a new workbook
my_workbook1= all_workbooks.OleFunction( "Add ");
