我已经学会了如何使用以下代码使用jxl库将颜色应用于excel表行的背景
WritableFont cellFonts = new WritableFont(WritableFont.ARIAL, 11, WritableFont.BOLD, false, UnderlineStyle.NO_UNDERLINE, jxl.format.Colour.BLACK);
WritableCellFormat cellFormats = new WritableCellFormat(cellFonts);
cellFormats.setBackground(Colour.AQUA);
但我不知道如何将自定义颜色应用为背景
当我尝试这个Colour myColour = Colour(221,221,221);
时,我得到了异常
WritableFont cellFonts = new WritableFont(WritableFont.ARIAL, 11, WritableFont.BOLD, false, UnderlineStyle.NO_UNDERLINE, jxl.format.Colour.BLACK);
WritableCellFormat cellFormats = new WritableCellFormat(cellFonts);
Colour myColour = Colour(221,221,221);
cellFormats.setBackground(myColour);
任何人都可以告诉我一些解决方案吗
答案 0 :(得分:0)
首先你需要创建一个方法:
private final WritableCellFormat getCellFormat(Colour colour) throws WriteException {
WritableFont cellFonts = new WritableFont(WritableFont.ARIAL, 11, WritableFont.BOLD, false, UnderlineStyle.NO_UNDERLINE, jxl.format.Colour.BLACK);
WritableCellFormat cellFormats = new WritableCellFormat(cellFonts);
myColour= new Colour(10000, "1", 221, 221, 221) {
};
cellFormats.setBackground(myColour);
return cellFormats;
}
你需要: 改变这个:
Colour myColour = Colour(221,221,221);
cellFormats.setBackground(myColour);
到此:
myColour= new Colour(10000, "1", 221, 221, 221) {
};
并在单元格中设置:
Label label1 = new Label(column, row, "text of cell or nothing", getCellFormat(myColour));
我希望有所帮助。
