问题描述
要在Apache POI 3.7及更低版本中为XSSFWorkbook应用自定义颜色,可以使用以下内容:
To apply a custom color for an XSSFWorkbook in Apache POI 3.7 and below the following was possible:
java.awt.Color c = new java.awt.Color (1,2,3)
XSSFCellStyle xcs = xssfWorkbook.createCellStyle();
XSSFFont headerFont = xssfWorkbook.createFont();
headerFont.setColor(new XSSFColor(c));
xcs.setFont(headerFont);
cell.setCellStyle(xcs);
在版本4.0中,XSSFColor(java.awt.Color)被删除了。只有额外的'hackery'仍然可以
达到相同的效果:
In version 4.0 XSSFColor(java.awt.Color) got removed. It is still possible to achieve the same, just with additional 'hackery':
XSSFColor xc = new XSSFColor();
xc.setARGBHex(String.format("%02x%02x%02x",c.getRed(),c.getGreen(),c.getBlue()));
headerFont.setColor(xc);
但这样做的正确方法是什么?大多数XSSFColor方法都涉及一个IndexedColorMap,但我找不到任何关于如何在XSSFWorkbook中设置自定义颜色的示例。
But what is the 'proper' way to do this? Most of the XSSFColor methods involve an IndexedColorMap but I could not find any example for how this could be used for setting custom colors in an XSSFWorkbook.
推荐答案
byte[] rgb = {120, 100, (byte) 200};
headerFont.setColor(new XSSFColor(rgb, new DefaultIndexedColorMap()));
