Apache POI Drawing Border

Apache POI allows us to apply a set of borders in our workbook sheet. The PropertyTemplate object simulates this with methods and constants defined to allow drawing top, bottom, left, right, horizontal, vertical, inside, outside borders of cells.

Lets see an example in which we are drawing border around the cells.

  package poiexample;  import java.io.FileOutputStream;  import java.io.OutputStream;  import org.apache.poi.hssf.usermodel.HSSFWorkbook;  import org.apache.poi.ss.usermodel.BorderExtent;  import org.apache.poi.ss.usermodel.BorderStyle;  import org.apache.poi.ss.usermodel.IndexedColors;  import org.apache.poi.ss.usermodel.Sheet;  import org.apache.poi.ss.usermodel.Workbook;  import org.apache.poi.ss.util.CellRangeAddress;  import org.apache.poi.ss.util.PropertyTemplate;  public class DrawingBorderExample {  public static void main(String[] args) {  try (OutputStream os = new FileOutputStream(“tutoraspire.xls”)) {   PropertyTemplate pt = new PropertyTemplate();   pt.drawBorders(new CellRangeAddress(1, 2, 1, 2),            BorderStyle.MEDIUM, BorderExtent.ALL);   pt.drawBorders(new CellRangeAddress(5, 6, 1, 2),            BorderStyle.MEDIUM, BorderExtent.OUTSIDE);   pt.drawBorders(new CellRangeAddress(5, 6, 1, 2), BorderStyle.THIN,            BorderExtent.INSIDE);   pt.drawBorders(new CellRangeAddress(9, 10, 1, 3),            BorderStyle.MEDIUM, IndexedColors.GREEN.getIndex(),            BorderExtent.OUTSIDE);   pt.drawBorders(new CellRangeAddress(9, 10, 1, 3),            BorderStyle.MEDIUM, IndexedColors.BLUE.getIndex(),            BorderExtent.INSIDE_VERTICAL);   pt.drawBorders(new CellRangeAddress(9, 10, 1, 3),            BorderStyle.MEDIUM, IndexedColors.RED.getIndex(),            BorderExtent.INSIDE_HORIZONTAL);   pt.drawBorders(new CellRangeAddress(10, 10, 2, 2),            BorderStyle.NONE,             BorderExtent.ALL);   Workbook wb = new HSSFWorkbook();   Sheet sheet = wb.createSheet(“Sheet”);   pt.applyBorders(sheet);   wb.write(os);  }catch(Exception e) {  System.out.println(e.getMessage());  }  }  }
