获取单元格之后我们需要对单元格进行操作，比如过单元格宽、单元格高、单元格背景色、单元格边框等等。
App = new Application(); //创建 Excel对象
object missing = Missing.Value; //获取缺少的object类型值
wb = App.Workbooks.Open(ExcelName, missing, missing, missing, missing,
missing, missing, missing, missing, missing, missing, missing, missing, missing, missing); //打开指定的Excel文件
Worksheet ws3 = ((Worksheet)wb.Worksheets["刀具预估数量"]);//方法一：指定工作表名称读取
//--------------------------获取专案名称--------------------------
string newtitle = ((Range)ws2.Cells[1, 1]).Text;//获取单元格内容
string[] Case = newtitle.Split('刀'); //分割获取到的内容
ws3.get_Range("A1", "Q1").Merge(0);//合并单元格
ws3.get_Range("A1", "Q1").HorizontalAlignment = XlHAlign.xlHAlignCenter; //文本居中显示
ws3.get_Range("A1", "Q1").Font.Size = 18; //设置字体大小
ws3.get_Range("A1", "Q1").Font.Bold = true; //设置字体为粗体
ws3.Cells[1, 1] = Case[0] + "刀具预估数量";
ws3.get_Range("A2", "Q2").Borders.LineStyle = 1;//设置表格的线宽
ws3.get_Range("A2", "Q2").Interior.ColorIndex = 14;//填充背景色
ws3.get_Range("A2").ColumnWidth = 5; //固定宽度
ws3.get_Range("B2").ColumnWidth = 8;
ws3.get_Range("C2").ColumnWidth = 25;
ws3.get_Range("D2").ColumnWidth = 12;
ws3.get_Range("E2").ColumnWidth = 10;
ws3.get_Range("F2", "Q2").ColumnWidth = 10; //固定宽度
//ws3.get_Range("F2", "Q2").Columns.AutoFit();//列表宽度自适应除了获取通过get_Range来Excel的单元格，我们也可以通过指定的下标来获取对应的单元格,即Cells[行, 列]
App = new Application(); //创建 Excel对象
object missing = Missing.Value; //获取缺少的object类型值
wb = App.Workbooks.Open(ExcelName, missing, missing, missing, missing,
missing, missing, missing, missing, missing, missing, missing, missing, missing, missing); //打开指定的Excel文件
Worksheet ws3 = ((Worksheet)wb.Worksheets["刀具预估数量"]);//方法一：指定工作表名称读取
//--------------------------获取专案名称--------------------------
string newtitle = ((Range)ws2.Cells[1, 1]).Text;//获取单元格内容
string[] Case = newtitle.Split('刀'); //分割获取到的内容
ws3.get_Range("A1", "Q1").Merge(0);//合并单元格
ws3.Cells[1, 1].HorizontalAlignment = XlHAlign.xlHAlignCenter; //文本居中显示
ws3.Cells[1, 1].Font.Size = 18; //设置字体大小
ws3.Cells[1, 1].Font.Bold = true; //设置字体为粗体
ws3.Cells[1, 1] = Case[0] + "刀具预估数量";
ws3.Cells[2, 1].Borders.LineStyle = 1;//设置表格的线宽
ws3.Cells[2, 1].Interior.ColorIndex = 14;//填充背景色
ws3.Cells[2, 1].ColumnWidth = 5; //固定宽度
ws3.Cells[2, 1].Columns.AutoFit();//列表宽度自适应
