Can I create a freeze pane and a split pane in the same sheet at once using Apache POI?

Question

I am using Apache POI XSSF and HSSF API.

If I do this, it only freezes the pane (no split):

sheet1.createSplitPane(8000, 5000, 0, 0, Sheet.PANE_LOWER_RIGHT);
sheet1.createFreezePane(0, 1); 

and if I do this, it only splits the pane (no freeze):

sheet1.createFreezePane(0, 1); 
sheet1.createSplitPane(8000, 5000, 0, 0, Sheet.PANE_LOWER_RIGHT); 

How should I make both work together in the same sheet?

Answer 1

As far as I can tell, Excel doesn't support having both a freeze pane and a split pane in the same sheet. This link appears to indicate that Excel doesn't allow it.

Regardless of whether Excel does/will allow it, POI doesn't support it either.

The Javadocs for createSplitPane explicitly state:

Creates a split pane. Any existing freezepane or split pane is overwritten.

and the Javadocs for createFreezePane say something similar.

Creates a split (freezepane). Any existing freezepane or split pane is overwritten.

Also, just opening up Excel (I have Excel 2010), if I create a split pane, then a freeze pane, the split pane disappears. If I then create a split pane, then the freeze pane disappears.

Excel (at least through 2010) doesn't appear to support both a freeze pane and a split pane simultaneously, and Apache POI respects that fact.
