How to create a cell with several styles in excell using HSSFSheet Apache POI?

Question

I am creating a script to export a document as excel. I found some difficulties in that: I want the cell value to be " Name: Mark DOB: 11-11-2014" by merging several cells. Can you help me solve this problem?

Thanks in advance!

Answer 1

What you need to do is create a RichTextString for your cell. This is a way to apply different formatting / styles for different parts of the same cell for display in Excel

POI " " , , , -

    Cell cell = row.createCell(1);
    RichTextString rt = new XSSFRichTextString("The quick brown fox");

    Font font1 = wb.createFont();
    font1.setBoldWeight(Font.BOLDWEIGHT_BOLD);
    rt.applyFont(0, 10, font1);

    Font font2 = wb.createFont();
    font2.setItalic(true);
    font2.setUnderline(XSSFFont.U_DOUBLE);
    rt.applyFont(10, 19, font2);

    Font font3 = wb.createFont();
    font3.setBoldWeight(Font.BOLDWEIGHT_NORMAL);
    rt.append(" Jumped over the lazy dog", font3);

    cell.setCellValue(rt);
