求教,C#导出Excel时设置列宽和边框

XSSFWorkbook xssfworkbook = new XSSFWorkbook();
ICellStyle cellStyle = xssfworkbook.CreateCellStyle();
cellStyle.BorderBottom = NPOI.SS.UserModel.BorderStyle.THIN;
cellStyle.BorderLeft = NPOI.SS.UserModel.BorderStyle.THIN;
cellStyle.BorderRight = NPOI.SS.UserModel.BorderStyle.THIN;
cellStyle.BorderTop = NPOI.SS.UserModel.BorderStyle.THIN;
ISheet sheet = xssfworkbook.CreateSheet(name);
sheet.SetColumnWidth(0, 10 * 256);（第1列）
sheet.SetColumnWidth(1, 10 * 256);（第2列）
......................................................

就是这样设置
