I have to delete a selected row in JTable using the Key Event. When I select a row and press the Delete Key, the selected row values should be deleted. How can I do this?

推荐答案

您必须获取选定的行(即光标当前所在的行)，然后在该行上调用removeRow.

You have to get the selected Rows (thats where the curser currently is) and then call removeRow on that rows.

我建议您阅读 JTable的API

尝试一下(我在使用代码的地方在代码中使用了多行，但是您应该可以将其分解为一行.而且，我不确定Arrays.sort是否真的必要)

try this (I used multiple rows in the code where I used it, but you should be able to break it down to one. Also, I'm unsure if the Arrays.sort is really necessary)

int [] toDelete = dataTable.getSelectedRows();
Arrays.sort(toDelete); // be shure to have them in ascending order.
MyTableModel myTableModel = (MyTableModel)dataTable.getModel();
for(int ii = toDelete.length -1; ii >=0; ii--) {
    myTableModel.removeRow(toDelete[ii]); // beginning at the largest.
}
