How can add different colour for each worksheet in excel using Apache POI

问题

When you have multiple worksheets in a workbook, you usually click on a sheet's name at the bottom of the page to view it. My question is then to know, if that "button" containing the sheet's name can take a color such as blue, green and so on.

    XSSFWorkbook wb = new XSSFWorkbook(); 
    XSSFSheet sheet = wb.createSheet(); 
    CTColor color = CTColor.Factory.newInstance(); 
    color.setIndexed(IndexedColors.RED.getIndex()); 
    sheet.getCTWorksheet().getSheetPr().setTabColor(color); 

I have tried above but no use

        try (XSSFWorkbook wb = new XSSFWorkbook()) {

        XSSFSheet sheet1 = wb.createSheet("1e");



        XSSFSheet sheet = wb.createSheet("1econtent");
        XSSFFont font = wb.createFont();
        font.setFontHeightInPoints((short) 15);
        font.setColor(IndexedColors.WHITE.getIndex());

        How can I add different colours sheet and sheet1 in workbook

回答1:

Please do it as follows:

sheet.setTabColor(IndexedColors.RED.getIndex());

Please check https://poi.apache.org/apidocs/dev/org/apache/poi/ss/usermodel/IndexedColors.html for more details.

EDIT:

Please do it as follows with the latest version of Apache POI:

byte[] rgb=DefaultIndexedColorMap.getDefaultRGB(IndexedColors.RED.getIndex());
sheet.setTabColor(new XSSFColor(rgb,null));
