if you want to get the data in the entire row, you can use this combination below
如果要获取整行的数据，可以使用下面这个组合
tableModel.getDataVector().elementAt(jTable.getSelectedRow());
Where "tableModel" is the model for the table that can be accessed like so
其中“tableModel”是可以像这样访问的表的模型
(DefaultTableModel) jTable.getModel();
this will return the entire row data.
这将返回整个行数据。

You can use the following code to get the value of the first column of the selected row of your table.
您可以使用以下代码获取表格中所选行的第一列的值。
int column = 0;
int row = table.getSelectedRow();
String value = table.getModel().getValueAt(row, column).toString();

using from ListSelectionModel:
使用来自ListSelectionModel：
ListSelectionModel cellSelectionModel = table.getSelectionModel();
cellSelectionModel.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
cellSelectionModel.addListSelectionListener(new ListSelectionListener() {
public void valueChanged(ListSelectionEvent e) {
String selectedData = null;
int[] selectedRow = table.getSelectedRows();
int[] selectedColumns = table.getSelectedColumns();
for (int i = 0; i < selectedRow.length; i++) {
for (int j = 0; j < selectedColumns.length; j++) {
selectedData = (String) table.getValueAt(selectedRow[i], selectedColumns[j]);
}
}
System.out.println("Selected: " + selectedData);
}
});
