so suchen Sie nach Daten in der jtable mit jtextfield?

Um die Suche nach etwas auf dem Tisch Sie haben, um den ursprünglichen Inhalt gespeichert, die in einigen Variablen.Im folgenden Beispiel habe ich gespeichert, die ursprünglichen Werte der Tabelle Modell zu einem Vektor.

Es gibt zwei Implementierungen unten.Eine Suche, sobald Sie etwas auf textfield, andere suchen nur nach einer Schaltfläche geklickt wird.

Für die erste Verwendung einer documentListener, Dinge zu tun für Sie.

Den unter Funktion entfernen werden die Werte in der Tabelle[für den Fall, wenn keine übereinstimmung gefunden, wird die Tabelle leer sein] und die Suche nach einem string in allen Zellen, und wenn eine übereinstimmung gefunden wird, wird es fügen Sie diese Zeile der Tabelle.

public void searchTableContents(String searchString) {    
  DefaultTableModel currtableModel = (DefaultTableModel) table.getModel();
    //To empty the table before search
    currtableModel.setRowCount(0);
    //To search for contents from original table content
    for (Object rows : originalTableModel) {
        Vector rowVector = (Vector) rows;
        for (Object column : rowVector) {
            if (column.toString().contains(searchString)) {
                //content found so adding to table
                currtableModel.addRow(rowVector);
                break;
            }
        }

    }
}
