SWT TableViewer页眉-高度

Question

我正在更改SWT Tableviewer的fontsize，但是表头的高度没有改变，因此标签被剪掉了。有没有办法解决这个问题？

(这是在Windows上)

Answer 1

Table 隶属于SWT，另一个TableViewer 隶属于 JFace。因此，您是否需要针对TableViewer或Table的解决方案尚不清楚。同样在你方没有任何代码片段的情况下，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不同。

检查// FOCUS ON THIS PART - START和// FOCUS ON THIS PART - END注释之间的代码。

此外，您不能为设置标题图像执行此操作。请参阅Table Header Image Bug
