SWT TableViewer 标题高度

Question

我正在更改 SWT Tableviewer 的字体大小，但表头的高度没有改变，因此标签被切断了。有没有办法解决这个问题？

（这是在 Windows 上）

Answer 1

Table 降级 SWT和另一个TableViewer 降级 JFace。所以不清楚您是否需要TableViewer 或Table 的解决方案。同样，在您没有任何代码 sn-p 的情况下，我选择为JFace 和TableViewer 演示它，尽管Table 和SWT 的概念将保持不变。

您可以看到标题高度的差异。

您也不能这样做来设置标题图像。见Table Header Image Bug
