 i.页面水平居中：
 ExcelApp.ActiveSheet.PageSetup.CenterHorizontally := 2/0.035;
 j.页面垂直居中：
 ExcelApp.ActiveSheet.PageSetup.CenterVertically := 2/0.035;
 k.打印单元格网线：
 ExcelApp.ActiveSheet.PageSetup.PrintGridLines := True;
15) 拷贝操作：
 a.拷贝整个工作表：
 ExcelApp.ActiveSheet.Used.Range.Copy;
 b.拷贝指定区域：
 ExcelApp.ActiveSheet.Range[ 'A1:E2' ].Copy;
 c.从A1位置开始粘贴：
 ExcelApp.ActiveSheet.Range.[ 'A1' ].PasteSpecial;
 d.从文件尾部开始粘贴：
 ExcelApp.ActiveSheet.Range.PasteSpecial;
16) 插入一行或一列：
 a. ExcelApp.ActiveSheet.Rows[2].Insert;
 b. ExcelApp.ActiveSheet.Columns[1].Insert;
17) 删除一行或一列：
 a. ExcelApp.ActiveSheet.Rows[2].Delete;
 b. ExcelApp.ActiveSheet.Columns[1].Delete;
18) 打印预览工作表：
 ExcelApp.ActiveSheet.PrintPreview;
19) 打印输出工作表：
 ExcelApp.ActiveSheet.PrintOut;
20) 工作表保存：
 if not ExcelApp.ActiveWorkBook.Saved then
 ExcelApp.ActiveSheet.PrintPreview;
21) 工作表另存为：
 ExcelApp.SaveAs( 'C:\Excel\Demo1.xls' );
22) 放弃存盘：
 ExcelApp.ActiveWorkBook.Saved := True;
23) 关闭工作簿：
