如何使用JExcel删除表格Excel表格

Question

I am trying to remove sheets from an existing excel file using jxl api.

I cannot use

WritableWorkbook wwb = new Workbook.createWorkbook("abc.xls");

as I do not want to create a new workbook, rather I want to use an existing one.

I cannot use

Workbook wb = new Workbook.getWorkbook("abc.xls");

as this would get the file in read only mode. There is no " getWorkbook " method for the class WritableWorkbook . Please tell me how to go about it.

I searched through examples online but in each case a new workbook is being created rather than using an existing one.

Answer 1

If you want to edit an existing excel file,you can do like this：

//Get the existing excel file
  Workbook file=Workbook.getWorkbook(new File("test.xls"));
//Open a copy of the excel file,and specify the parameters to write the data back
//to the original file.
  WritableWorkbook writeBook=Workbook.createWorkbook(new File("test.xls"),file);
  writeBook.removeSheet(0);

Answer 2

WritableWorkbook wwb = new Workbook.createWorkbook("abc.xls");

This line is wrong. You can't use "new" since the class Workbook is a factory that returns a new Workbook. Try this:

WritableWorkbook wwb = Workbook.createWorkbook("abc.xls");

Answer 3

Call removeSheet on the workbook instance? It's right there in the documentation...
