Sorry for the short post it was my first ....My problems was really to do with changing the row height depending on the content. So what i have done so far is made a inner class that implements TabelCellRenderer.
抱歉，这是我的第一篇短文……我的问题实际上与根据内容更改行高有关。所以到目前为止我所做的是一个实现 TabelCellRenderer 的内部类。
This is what i am doing at the moment for my row height calculations.
这就是我目前为行高计算所做的事情。
private static class TextAreaRenderer extends JTextPane implements TableCellRenderer
{
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected,
boolean hasFocus, int row,
int column)
{
/* Setup Code here */
this.setText(((String)value).getEntityName());
int height = new Double(this.getPreferredSize().getHeight()).intValue();
if (table.getRowHeight(row) < height)
table.setRowHeight(row, height);
/* some more code */
return this;
}
}
}
Would this be the correct way to do this ? Thanks.
这是正确的方法吗？谢谢。

You simply call setRowHeight(row, height);. For example:
您只需调用setRowHeight(row, height);. 例如：
JTable t = new JTable(5, 5);
t.setRowHeight(2, 30);
will set the 3rd row to 30 high.
将第 3 行设置为 30 高。
Is your question more complicated? You haven't said much about the problem.
你的问题比较复杂？你没有说太多关于这个问题。
