I have a JTable where a series of Float are displayed. For small values the cell displays the number in scientific notation. Is there a way to disable that?

推荐答案

您应该阅读以下页面，以了解发生这种情况的原因:

You should read the following page to get an insight about why it is happening: http://docs.oracle.com/javase/tutorial/uiswing/components/table.html#editrender

然后，您应该将自己的NumberFormat实例(以某种方式)传递到您的JTable中，然后所有数字都将正确格式化.

Then you should pass your own NumberFormat instance (somehow) in to your JTable, and then all numbers will be formatted properly.

如果您决定长时间使用它，我认为通读整个JTable文档是一本好书，并且我确信在那里提到了如何应用NumberFormat.

I think it's a good read to read through the entire JTable documentation if you decide to work with it for a long time and I am sure that it is mentioned there how to apply the NumberFormat.
