具有复杂格式的 JTable
JTable with complex formatting
我需要制作一个 JTable，其中每个“单元格”都有各种单独的数据要显示。我需要为每个项目显示目标值、实际值、预计值以及三者之间的差值，包括占总价值的百分比和美元价值。附加图像是在 Excel 中完成的，但显示了我试图在 JTable 中生成的内容。
为了让事情变得更有趣，除了目标和实际值行之外，所有其他行都是由用户在 运行 时选择的table。因为他们可以通过在我的程序中选择选项来选择要显示的行。我需要能够在逐个子单元格的基础上自定义单元格底纹、字体和文本格式，我还需要在整个 table.[= 中改变边框、行高和列宽。 11=]
我还没有开始编写代码，因为我正在考虑不同的方法。我正在寻找其他人关于采用哪种方法的反馈，或者是否还有其他我应该考虑的选择。
选项 1 - 只需将单个 JTable 与自定义数据模型一起使用，但在其他方面尽可能接近默认的单元格渲染器和单元格编辑器，并使用每个单元格的边框和格式来模仿预期的外观-n-感觉。数据模型将处理 JTable 提供的行、列的转换，以及 item/value 每个单元格实际对应的内容。
选项 2 - 使用 JTable 作为 JTable 中每个单元格的单元格编辑器（table 中的 table）。
选项 3 - 使用各种标签和文本字段编写我自己的自定义单元格渲染器。
选项 4 - 是否有任何预先编写的组件可以提供我正在寻找的那种我应该考虑的灵活性？
对采取最佳方法的想法表示赞赏。
谢谢。
