我想设置一些自定义(从十六进制或RGB值)颜色到一个xssfcell.But单元格的颜色变成黑色,即使我给一些其他颜色。我试图通过以下方式这样做:无法在XSSFCell中设置自定义颜色Apache POI
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);
// END程序
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
我试图在回答有关问题提到的其他许多方面,但这些都不解决我的问题。 请帮我一把。
这是早上在这里,但1和3有什么区别?我认为你错过了一个填充模式,请参阅https://stackoverflow.com/a/31671032/180100 – 2017-07-16 09:00:03
当然,我会用最少的代码更新这个问题。谢谢 – Pranjal
填充模式在代码中并不缺少,如果填充图案丢失了,即使设置了颜色后,细胞仍然是全白的。但在我的情况下,全细胞是黑色的。 – Pranjal
