将视图设置为特定单元格

Question

您知道如何将视图设置为JTable 中的特定单元格吗？ 因为我正在搜索单元格中的特定内容（例如 Ctrl + F）

我有一个特定的单元格，例如第 39 行和第 5 列，但我不知道如何查看它

我查看了JTable 和DefaultTableModel，但没有看到任何有用的方法。

如果您想选择（突出显示）特定的 JTable Cell，那么这可能是您可以做到的一种方式：

public static void selectJTableCell(javax.swing.JTable theTable, 
                         int literalCellRowNumber, int literalCellColumnNumber) {
    /* Set the Selection mode...   */
    theTable.setSelectionMode(javax.swing.ListSelectionModel.SINGLE_INTERVAL_SELECTION);
    /* Make sure ColumnSelectionAllowed is enabled 
      so that just the cell is selected.        */
    theTable.setColumnSelectionAllowed(true);
    /* Make sure RowSelectionAllowed is enabled. 
       (It should be by default anyways).     */
    theTable.setRowSelectionAllowed(true);
    /* Select the desired cell. We subtract 1 from 
       the supplied LITERAL Cell Row Number and the
       LITERAL Cell Column Number values supplied 
       since we're asking for the literal row/column
       numbers rather than index numbers. If you would 
       rather use an index value then remove the -1's.  */
    theTable.changeSelection(literalCellRowNumber - 1, literalCellColumnNumber - 1, false, false);
}

如何使用此方法：

selectJTableCell(jTable1, 39, 5);

因此，如果您想选择整个 JTable 行，那么这可能是您可以做到的一种方式：

public static void selectJTableRow(javax.swing.JTable theTable, int literalRowNumber) {
    /* Subtract 1 from the supplied LITERAL Row 
       Number value supplied since we're asking 
       for the literal row number rather than the 
       index number. If you would rather use an 
       index value then remove this code line.  */
    literalRowNumber = literalRowNumber - 1;
    /* Disable ColumnSelectionAllowed otherwise the 
       row will not be highlighted.        */
    theTable.setColumnSelectionAllowed(false);
    /* Make RowSelectionAllowed is enabled.*/  
    theTable.setRowSelectionAllowed(true);
    /* Select the first cell in the desired row to 
       ensure the table will scroll to the row 
       selection so that it will be visible within 
       the viewport.                */
    theTable.changeSelection(literalRowNumber, 0, false, false);
    // Now, Select the row.
    theTable.setRowSelectionInterval(literalRowNumber, literalRowNumber);
    
}

如何使用此方法：

selectJTableRow(jTable1, 39);
