使用向量字符串刷新JTable

Question

我試圖刷新我的表，但它不會刷新。我嘗試使用fireTableDataChanged（）以及創建一個新模型，但我的表不會退步。我可以獲取初始值，但我無法弄清楚如何刷新它。 HS = new Vector（Arrays.asList（finalHSArr））; SF = new Vector（Arrays.asList（finalFlagsArr））; 我有兩個單獨的JTable，我試圖刷新，這些是上面的新值。我一直在嘗試6個小時。

Answer 1

當你

HS = new Vector<String>(Arrays.asList(finalHSArr)); 
SF = new Vector<String>(Arrays.asList(finalFlagsArr)); 

你改變什麼HS和SF哪裏點，但是，它並沒有改變什麼，在內部，TableModel所指向。

您可以使用DefaultTableModel#setDataVector，但我可能會更簡單，只需簡單地創建新的TableModel s並將其設置爲JTable即可。

hsTableModel = new DefaultTableModel(HS, column); 
hotelSecurityTable.setModel(hsTableModel); 

sfTableModel = new DefaultTableModel(HS, column); 
securityFlagsTable.setModel(sfTableModel); 

因爲它幾乎是同樣的事情...

更新

DefaultTableModel期待Vector的Vector一個S，但你提供String的Vector秒。

嘗試類似...

hsTableModel.setRowCount(0); 
for (String row : HS) { 
    hsTableModel.addRow(new Object[]{row}); 
} 

，而不是...
