[英]Java: JTable adding and moving columns
im quite new in Java. 我在Java中相当新。 I want to add Columns in a JTable at a specified index.
我想在JTable中的指定索引处添加列。 For this i am using addColumn(..) and then move them with moveColumn(...), this works great at the first time, but when i add another column it kind of moves also the other(before added columns).
为此,我使用addColumn(..),然后使用moveColumn(...)将其移动,这在第一次使用时效果很好,但是当我添加另一列时,它也会移动另一列(在添加列之前)。
Do you have any suggestions? 你有什么建议吗?
this is the code i've written in the TableModel is: 这是我在TableModel中编写的代码是:
public void addColumn(Object columnName,
Vector columnData, JTable table) {
int moveTo = ((Integer)columnName);
boolean unselected = moveTo==-1;
super.addColumn(this.getColumnCount(), columnData);
if(!unselected) {//if a column was selected
table.moveColumn(this.getColumnCount()-1, moveTo+1);
}
}
this works great at the first time, but when i add another column it kind of moves also the other(before added columns).
这在第一次时效果很好,但是当我添加另一列时,它也会移动另一列(在添加列之前)。
I don't understand what that means. 我不明白那是什么意思。
