测量 SWT/JFace 列标题填充大小
我的 eclipse SWT 应用程序中有许多表。它们是 Table/TableViewer 表格，由标题、左侧一行文字和一系列图形组成。除文本列外还有 32 列，编号从 0 到 31。 在 Windows 7 和 XP 的经典模式下，文本很好，但在 XP 正常模式下，它们被截断，因此看起来为 0 1 2 3 4 5 6 7 8 9 1. 1. 1. 1. 1. 等。无论哪种方式，文本显然都有足够的空间。
如果我只是将默认宽度设置为 28 而不是 25，正如我发现的那样，它们就很好，但显然这不是很好，因为那时我需要更多的空间用于 Windows 7 和 XP Classic 中的界面，其中它是已经可以了。 我尝试从 fontmetrics 获取平均宽度，但在所有模式下文本返回为 5。我找不到任何方法来减少填充（这将是最好的方法），或找出有多少填充（这将是）。我需要手动绘制列标题吗？
ps：对 JFace / SWT 感到抱歉，才刚刚开始使用，还不清楚其中的差异！
I have a number of tables in an eclipse SWT application. They are Table/TableViewer tables and consist of a header, a row down the left with text and a series of graphics going across. There are 32 columns other than the text column, numbered from 0 to 31.
On Windows 7 and XP in classic mode, the text is fine, but in XP normal mode, they are truncated so they appear to go 0 1 2 3 4 5 6 7 8 9 1. 1. 1. 1. 1. etc. There is clearly enough room for the text either way.
If I just set the default width to 28 instead of 25, as I found it, they are then fine, but obviously that isn't very good as then I need more room for the interface in Windows 7 and XP Classic, where it was already ok.
I tried getting average width from fontmetrics but the text comes back as 5, in all modes. I can't find any way of either reducing of the padding (which would be the best way), or finding out how much padding there is (which would do). Do I need to draw the column headers manually?
ps: Sorry for the JFace / SWT, have only just started with this and not clear on the differences yet!

调用 TableColumn#pack() 应该为列提供显示其内容所需的宽度，而不会浪费任何空间或截断其内容。这包括列的标题文本。
Calling
TableColumn#pack()should give a column exactly the width it needs to display its content without wasting any space or truncating its content. This includes the column's header text.您应该使用 TableLayout 对表格标题进行更动态的大小计算。以下博客文章是一个很好的起点： http ://eclipsenuggets.blogspot.com/2007/11/one-of-less-prominent-novelties-in.html
You should use the TableLayout for a more dynamic size calculation of your table headers. A good starting point is the following blog article: http://eclipsenuggets.blogspot.com/2007/11/one-of-less-prominent-novelties-in.html
