我希望我的用户能够输入4个允许他们填充JTable的字段。我在CreateFxitures课程中有一个JPanel。在这个JPanel上，他们能够将数据输入两个ComboBoxes和2个TextFields。输入所有数据后，应单击Create按钮，将所有数据添加到输入表中的rowNames数组中。但是，当他们单击Create时，该行会创建一个新行，但不会添加数据。我该怎么做呢？

答案 0 :(得分：1)
首先使用getText()获取字段值。然后从值创建一个Object数组。然后像你一样使用addRow(array)。您当前尝试添加的数组包含所有空值。所以你只需要获取文本字段的当前值，然后用它们添加行。忘掉createCall.rowData。它没有为你做任何事。每按一次按钮，创建一个新的Object[]。像
String data1 = typeSTR.getText();
String data2 = descSTR.getText();
String data3 = monthSTR.getText();
String data4 = resultSTR.getText();
Object[] row = { data1, data2, data3, data4 };
model.addRow( row );
