ウィンドウ枠の分割と固定There are two types of panes you can create; freeze panes and split panes. A freeze pane is split by columns and rows. You create a freeze pane using the following mechanism: sheet1.createFreezePane( 3, 2, 3, 2 ); The first two parameters are the columns and rows you wish to split by. The second two parameters indicate the cells that are visible in the bottom right quadrant. Split pains appear differently. The split area is divided into four separate work area's. The split occurs at the pixel level and the user is able to adjust the split by dragging it to a new position. Split panes are created with the following call: sheet2.createSplitPane( 2000, 2000, 0, 0, HSSFSheet.PANE_LOWER_LEFT ); The first parameter is the x position of the split. This is in 1/20th of a point. A point in this case seems to equate to a pixel. The second parameter is the y position of the split. Again in 1/20th of a point. The last parameter indicates which pane currently has the focus. This will be one of HSSFSheet.PANE_LOWER_LEFT, PANE_LOWER_RIGHT, PANE_UPPER_RIGHT or PANE_UPPER_LEFT.
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet1 = wb.createSheet("new sheet");
HSSFSheet sheet2 = wb.createSheet("second sheet");
HSSFSheet sheet3 = wb.createSheet("third sheet");
HSSFSheet sheet4 = wb.createSheet("fourth sheet");
// Freeze just one row
sheet1.createFreezePane( 0, 1, 0, 1 );
// Freeze just one column
sheet2.createFreezePane( 1, 0, 1, 0 );
// Freeze the columns and rows (forget about scrolling position of the lower right quadrant).
sheet3.createFreezePane( 2, 2 );
// Create a split with the lower left side being the active quadrant
sheet4.createSplitPane( 2000, 2000, 0, 0, HSSFSheet.PANE_LOWER_LEFT );
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();
行と列の繰り返しIt's possible to set up repeating rows and columns in your printouts by using the setRepeatingRowsAndColumns() function in the HSSFWorkbook class. This function Contains 5 parameters. The first parameter is the index to the sheet (0 = first sheet). The second and third parameters specify the range for the columns to repreat. To stop the columns from repeating pass in -1 as the start and end column. The fourth and fifth parameters specify the range for the rows to repeat. To stop the columns from repeating pass in -1 as the start and end rows.
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet1 = wb.createSheet("new sheet");
HSSFSheet sheet2 = wb.createSheet("second sheet");
// Set the columns to repeat from column 0 to 2 on the first sheet
wb.setRepeatingRowsAndColumns(0,0,2,-1,-1);
// Set the the repeating rows and columns on the second sheet.
wb.setRepeatingRowsAndColumns(1,4,5,1,2);
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();
ヘッダ・フッタサンプルは、ヘッダに対するものですが、フッタにも直接あてはまります。

header.setCenter("Center Header");
header.setLeft("Left Header");
header.setRight(HSSFHeader.font("Stencil-Normal", "Italic") +
HSSFHeader.fontSize((short) 16) + "Right w/ Stencil-Normal Italic font and size 16");
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
