我正在尝试将一些自定义颜色(来自十六进制代码或RGB值)设置为xssfcell的颜色。但是,即使我给出其他颜色,单元格的颜色也会变成黑色。我已经尝试通过以下方式实现:
File xlSheet = new File("C:\\Users\\IBM_ADMIN\\Downloads\\Excel Test\\Something3.xlsx");
System.out.println(xlSheet.createNewFile());
FileOutputStream fileOutISPR = new FileOutputStream("C:\\Users\\IBM_ADMIN\\Downloads\\Excel Test\\Something3.xlsx");
XSSFWorkbook isprWorkbook = new XSSFWorkbook();
XSSFSheet sheet = isprWorkbook.createSheet("TEST");
XSSFRow row = sheet.createRow(0);
XSSFCellStyle cellStyle = isprWorkbook.createCellStyle();
byte[] rgb = new byte[3];
rgb[0] = (byte) 24; // red
rgb[1] = (byte) 22; // green
rgb[2] = (byte) 219; // blue
XSSFColor myColor = new XSSFColor(rbg);
cellStyle.setFillForegroundColor(myColor);
cellStyle.setFillPattern(CellStyle.SOLID_FOREGROUND);
cellStyle.setAlignment(HorizontalAlignment.CENTER);
XSSFCell cell = row.createCell(0);
cell.setCellValue("Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has");
cell.setCellStyle(cellStyle);
CellRangeAddress rangeAddress = new CellRangeAddress(0, 0, 0, 2);
sheet.addMergedRegion(rangeAddress);
int width = ((int)(90 * 0.73)) * 256;
sheet.setColumnWidth(cell.getColumnIndex(), width);
//sheet.autoSizeColumn(cell.getColumnIndex());
RegionUtil.setBorderBottom(XSSFCellStyle.BORDER_MEDIUM, rangeAddress, sheet, isprWorkbook);
RegionUtil.setBottomBorderColor(IndexedColors.RED.getIndex(), rangeAddress, sheet, isprWorkbook);
XSSFCell cell2 = row.createCell(11);
cell2.setCellValue("222222222222222");
isprWorkbook.write(fileOutISPR);
//程序结束
XSSFCellStyle cellStyle = isprWorkbook.createCellStyle();
byte[] rgb = new byte[3];
rgb[0] = (byte) 24; // red
rgb[1] = (byte) 22; // green
rgb[2] = (byte) 219; // blue
XSSFColor myColor = new XSSFColor(rgb);
cellStyle.setFillForegroundColor(myColor);//1st method
//cellStyle.setFillForegroundColor(new XSSFColor(new java.awt.Color(128, 0, 128)));//2nd method
//XSSFColor myColor = new XSSFColor(Color.decode("0XFFFFFF"));
cellStyle.setFillForegroundColor(myColor);//3rd Method
我尝试了许多其他问题答案中提到的方法,但都没有解决我的问题。请帮助我解决。
