How to check a column is hidden or not in excel file using apache poi

问题

I am trying to parse a xls file using apache poi. Is it possible to check whether a column is hidden or not. How can I get the width of a particular column.

Example: According to the post here it checks if the row is hidden or not.

Similarly I want to check the width of a column ( or check if the column is hidden or not)

回答1:

you can set a column as hidden/unhidden by using

 sheet.setColumnHidden(int columnIndex, boolean hidden); 

e.g.

 sheet.setColumnHidden(2, true);   // this will hide the column index 2
 sheet.setColumnHidden(2, false);   // this will unhide the column index 2

and the column is hidden or not can be checked using

  sheet.isColumnHidden(int columnIndex);

e.g.

  sheet.isColumnHidden(2);   //this will check the 2nd column index whether it is hidden or not

回答2:

The Sheet class has the method boolean isColumnHidden(int columnIndex) and also the method int getColumnWidth(int columnIndex), however the returned width is a unit of character width. Not sure if that helps you.
