问题描述

我在为 Apache POI XSSFWorkbook 设置自定义字体颜色时遇到了一些麻烦.当我这样做时:

I'm having a little trouble with setting a custom font color for an XSSFWorkbook from Apache POI. When I do:

    yellow = workbook.createCellStyle();
    Font whiteFont = workbook.createFont();
    whiteFont.setColor(new XSSFColor(new Color(255, 255, 255)).getIndexed());
    yellow.setFillForegroundColor(new XSSFColor(yellowRGB));
    yellow.setFillPattern(XSSFCellStyle.SOLID_FOREGROUND);
    yellow.setFont(whiteFont);

字体保持黑色,但是我不确定自己在做什么错.

The font stays black, I'm not sure what I'm doing wrong though.

推荐答案

您可以执行 whiteFont.setColor(new XSSFColor(new Color(255,255,255)));

但是,Apache POI中有一个错误,正在切换黑白.看来他们在 XSSFColor.java (请查看XSSFColor.correctRGB()),以解决Excel中的问题.Excel可能已修复,但Apache POI尚未更新.

However, there is a bug in Apache POI, where it is switching black and white. It looks like they put a 'fix' in XSSFColor.java (look at XSSFColor.correctRGB()) to correct for a problem in Excel. It's likely that Excel was fixed, but Apache POI wasn't updated.

您可以执行以下操作: whiteFont.setColor(HSSFColor.WHITE.index) whiteFont.setColor(IndexedColors.WHITE.index); (已弃用)

Instead you can do: whiteFont.setColor(HSSFColor.WHITE.index)or whiteFont.setColor(IndexedColors.WHITE.index); (this is deprecated)

或者如果您执行 whiteFont.setColor(new XSSFColor(new Color(255,255,254))); 它将非常接近白色.

or if you do whiteFont.setColor(new XSSFColor(new Color(255,255,254))); it'll be really close to white.
