从原表导出的编码 ：

导出

Dim flg As New SaveExcelFlags

flg.RowNumber = False

flg.CellStyle = True

Flg.VisibleOnly = True

Tables("杭康设备总表").SaveExcel("d:\\杭康设备(修检校)\\设备总表(临时文件)\\" & Date .Today & " 杭康设备.xls","杭康设备总表",flg)

Dim Proc As New Process

Proc.File = "d:\\杭康设备(修检校)\\设备总表(临时文件)\\" & Date .Today & " 杭康设备.xls"

Proc.Start()

（“是否报废”列是逻辑列，Xlsx表上单元格显示是  FALSE ），不知要怎么改？请老师帮助。
