我的问题是文本字段太长并且超出范围。我制作的表格由 5 行组成，但它往往会占用更多空间。我实际上想将 FREIGHT DETAILS 和 SALES DETAILS 平行对齐，用垂直线分隔。请帮助我编写代码来完成所有这些工作，以便我的表单看起来整洁且完全可见。

Answer 1

My problem is that the textfields are too long and go out of bounds.

我无法根据您发布的代码重现该问题。也许还有其他我没有看到的原因导致了这种行为。

I actually wanted to align the FREIGHT DETAILS & SALES DETAILS in parallel, separated using a vertical line.

即使使用第三方布局管理器，如 DesignGridLayout你可以关注Nested Layout使用 JPanel 对 cargo 详细信息和销售详细信息组件进行分组的方法。

关于垂直分隔符，不要认为它可以用 DesignGridLayout。虽然您可以让组件跨越多行，但它不适用于 JSeparator。

Please help me with code to do all this, so that my form looks neat and is fully visible.

StackOverflow 不是代码工厂，因此在大多数情况下，人们不会为您完成工作，但他们可以提供有用的示例。但是，由于我不得不复制您的所有代码来测试它，并且我使用嵌套布局方法进行了一些更改，因此我将在此处异常(exception)。希望对您有所帮助:
