Apache POI Cell Multiple Styles

To apply multiple styles and text formatting to a cell, Apache POI provides CellStyle feature. We can create CellStyle for the workbook and then apply text styling to the cell.

Apache POI Cell Multiple Style Example

  package poiexample;  import java.io.FileOutputStream;  import java.io.OutputStream;  import org.apache.poi.ss.usermodel.Row;  import org.apache.poi.ss.usermodel.Sheet;  import org.apache.poi.ss.usermodel.Workbook;  import org.apache.poi.xssf.usermodel.XSSFCell;  import org.apache.poi.xssf.usermodel.XSSFColor;  import org.apache.poi.xssf.usermodel.XSSFFont;  import org.apache.poi.xssf.usermodel.XSSFRichTextString;  import org.apache.poi.xssf.usermodel.XSSFWorkbook;  public class MultipleStylesExample {  public static void main(String[] args) {  try (OutputStream os = new FileOutputStream(“tutoraspire.xls”)) {   Workbook wb = new XSSFWorkbook();   Sheet sheet = wb.createSheet(“Sheet”);   Row row = sheet.createRow(2);   XSSFFont font1 = (XSSFFont) wb.createFont();   XSSFFont font2 = (XSSFFont) wb.createFont();   XSSFFont font3 = (XSSFFont) wb.createFont();   XSSFCell hssfCell = (XSSFCell) row.createCell(2);    XSSFRichTextString richString = new XSSFRichTextString( “Hello, World!” );    richString.applyFont( 0, 6, font1 );    richString.applyFont( 6, 13, font2 );    hssfCell.setCellValue( richString );    XSSFCell cell = (XSSFCell) row.createCell(1);    XSSFRichTextString rt = new XSSFRichTextString(“This is tutoraspire”);    font1.setBold(true);    font1.setColor(new XSSFColor(new java.awt.Color(255, 0, 0)));    rt.applyFont(0, 12, font1);    font2.setItalic(true);    font2.setUnderline(XSSFFont.U_DOUBLE);    font2.setColor(new XSSFColor(new java.awt.Color(0, 255, 0)));    rt.applyFont(12, 18, font2);    font3.setColor(new XSSFColor(new java.awt.Color(0, 0, 255)));    rt.append(” Learn New Technology Easily”, font3);    cell.setCellValue(rt);    wb.write(os);  }catch(Exception e) {  System.out.println(e);  }  }  }
