column.applyStyle (style, styleFlag); не дать правильный результат?

Question

Я пытаюсь форматировать данные столбца для числа. Ниже приведен код, который работает для Single cell.

//Instantiating a Workbook object 
Workbook workbook = new Workbook(); 

//Accessing the added worksheet in the Excel file 
int sheetIndex = workbook.getWorksheets().add(); 
Worksheet worksheet = workbook.getWorksheets().get(sheetIndex); 
Cells cells = worksheet.getCells(); 

//Adding the current system date to "A1" cell 
Cell cell = cells.get("A1"); 
cell.setValue(Calendar.getInstance()); 

//Setting the display format of the date to number 15 to show date as "d-mmm-yy" 
Style style = cell.getStyle(); 
style.setCustom("d-mmm-yy"); 
cell.setStyle(style); 

//Adding a numeric value to "A2" cell 
cell = cells.get("A2"); 
cell.setValue(20); 

//Setting the display format of the value to number 9 to show value as percentage 
style = cell.getStyle(); 
style.setCustom("0.0%"); 
cell.setStyle(style); 

//Adding a numeric value to "A3" cell 
cell = cells.get("A3"); 
cell.setValue(1546); 

//Setting the display format of the value to number 6 to show value as currency 
style = cell.getStyle(); 
style.setCustom("$#,##0;[Red]$-#,##0"); 
cell.setStyle(style); 

//Saving the modified Excel file in default format 
workbook.save("C:\\output.xls"); 

Вот код column.The ниже код не работает :(

//Instantiating a Workbook object 
Workbook workbook = new Workbook(); 

//Accessing the added worksheet in the Excel file 
int sheetIndex = workbook.getWorksheets().add(); 
Worksheet worksheet = workbook.getWorksheets().get(sheetIndex); 

Cells cells = worksheet.getCells(); 
Column column = cells.getColumns().get(30); 

Style style =column.getStyle(); 
style.setHorizontalAlignment(TextAlignmentType.CENTER); 
style.setCustom("$#,##0;[Red]$-#,##0"); 

StyleFlag styleFlag = new StyleFlag(); 

//Applying the style to the column 
column.applyStyle(style, styleFlag); 

//Saving the modified Excel file in default format 
workbook.save("C:\\output.xls"); 

Может кто-нибудь помочь в этом.

Вам необходимо установить соответствующие параметры форматирования на для StyleFlag объект, увидеть обновленный пример кода, который работает отлично: , например, код Пример:

//Instantiating a Workbook object 
     Workbook workbook = new Workbook(); 

     //Accessing the added worksheet in the Excel file 
     int sheetIndex = workbook.getWorksheets().add(); 
     Worksheet worksheet = workbook.getWorksheets().get(sheetIndex); 

     Cells cells = worksheet.getCells(); 
     Column column = cells.getColumns().get(30); 

     Style style1 = column.getStyle(); 
     style1.setHorizontalAlignment(TextAlignmentType.CENTER); 
     style1.setCustom("$#,##0;[Red]$-#,##0"); 

     StyleFlag styleFlag1 = new StyleFlag(); 
     styleFlag1.setNumberFormat(true); 
     styleFlag1.setHorizontalAlignment(true);  

     //Applying the style to the column 
     column.applyStyle(style1, styleFlag1); 

     //Saving the modified Excel file in default format 
     workbook.save("C:\\output.xls");
