Question

 我在后台用<SCRIPT LANGUAGE=\"VBScript\">
   javalist += " set excelobj=createobject(\"excel.application\") \r\n ";
            javalist += " excelobj.visible=true  \r\n";
            javalist += " set wk = excelobj.Workbooks.add  \r\n ";
            javalist += " set excelsheet =wk.Worksheets(\"sheet1\")\r\n ";            javalist += " excelsheet.Columns(\"a:a\").ColumnWidth = 12  \r\n ";
            javalist += " excelsheet.Columns(\"b:b\").ColumnWidth = 15   \r\n ";
            javalist += " excelsheet.Columns(\"c:c\").ColumnWidth = 30   \r\n ";
            javalist += " excelsheet.Columns(\"d:d\").ColumnWidth = 25   \r\n ";
            javalist += " excelsheet.Columns(\"e:e\").ColumnWidth = 40   \r\n ";
            javalist += " excelsheet.Columns(\"f:f\").ColumnWidth = 40   \r\n ";
            javalist += " excelsheet.Columns(\"g:g\").ColumnWidth = 10   \r\n ";
            javalist += " excelsheet.Columns(\"h:h\").ColumnWidth = 10   \r\n ";
            javalist += " excelsheet.Columns(\"i:i\").ColumnWidth = 10   \r\n ";
            javalist += " excelsheet.Columns(\"j:j\").ColumnWidth = 10   \r\n ";            //表头 
            //第1列
            javalist += " excelsheet.cells(1,1).HorizontalAlignment =3   \r\n";
            javalist += " excelsheet.cells(1,1).VerticalAlignment = 2   \r\n";
            javalist += " excelsheet.cells(1,1).value=\"编号\"   \r\n";
            javalist += " excelsheet.cells(1,1).Borders.LineStyle=1   \r\n";
string fileNumberStr  = "aaa；bbb；ccc0"
   javalist += " excelsheet.cells(" + y + ",1).value=\"" + fileNumberStr + "\" \r\n  ";
                    javalist += " excelsheet.cells(" + y + ",1).Borders.LineStyle=1  \r\n ";
打印生成excel表格时怎么在  aaa；加换行，bbb；加换行??????
