How do I use Apache POI to pre-define an auto-filter region in an Excel 2007 document?
A small code example or link would be nice.
Answer
Save the first and the last cell from the filter area, and execute:
sheet.setAutoFilter(new CellRangeAddress(firstCell.getRow(), lastCell.getRow(), firstCell.getCol(), lastCell.getCol()));
For example, from the sheet below.
>x (x, y)
0123456
0|--hhh--| h = header
1|--+++--| + = values
2|--+++--| - = empty fields
3|--+++--|
4|-------|
fist cell will be the header above the first + (2,1) cell. The the last will be the last + cell (5,3)
