Resizing JTable columns automatically based on text size
提问by David
I have a JTable with some fields with long text and some with little text.
我有一个 JTable，其中一些字段带有长文本，一些字段带有少量文本。
By default, this is how it looks:
默认情况下，它是这样的：
Notice how the "Name" and "Title" rows are not shortened.
请注意“名称”和“标题”行没有缩短。
I would like to know two things:
我想知道两件事：
- How to manually set the width of Headers(Such as Name, Title, Surname)
- How to automatically resize all of them depending on the text.
- 如何手动设置标题的宽度（如姓名、职务、姓氏）
- 如何根据文本自动调整所有大小。
Here is the code:
这是代码：
String[] columnNames = {"Name", "Title", "Surname", "ID"};
Object[][] testData = {
{"John", "Mr.", "Doe", "61020384U"},
};
nameTable = new JTable(testData, columnNames);
nameTable.setFont(new Font("Tahoma", Font.PLAIN, 11));
window.add(new JScrollPane(nameTable));
I have looked at the Swing Tutorialsbut I either must have missed something or it isn't there.
我看过Swing 教程，但我一定是漏掉了一些东西，或者它不存在。

I think that by defalut is there 80pixels, but you can change that with follows, for example ...
我认为默认情况下有 80pixels，但您可以通过以下方式更改它，例如......
TableColumnModel tcm = myTable.getColumnModel();
tcm.getColumn(0).setPreferredWidth(100); //Name
tcm.getColumn(1).setPreferredWidth(40); //Title
tcm.getColumn(2).setPreferredWidth(400); //Surname
tcm.getColumn(3).setPreferredWidth(40); //ID
