java - 线程“AWT-EventQueue-0”中的异常java.lang.ArrayIndexOutOfBoundsException:0> = 0

有人可以向我解释这个错误，我不明白发生了什么吗？
正在尝试重置JTable，因此每次我调用cargartablaclientes方法时，它都不会添加更多行。
然后加载表格

public void agregarnuevafila(javax.swing.JTable Table)
{
   //Define temp como una variable de tipo DefaultTableModel
   DefaultTableModel temp = (DefaultTableModel) Table.getModel();
   Object nuevo[] = {"","","","","","",""};

   //Inserta la nueva fila al objeto correspondiente
   temp.addRow(nuevo);
}

public void cargartablaclientes(javax.swing.JTable jTable1, String fech)
{
    int linea = 1;
    reiniciarJTable(jTable1);
    try
    {
        Connection cn = sql.Conectar();

        String query = "SELECT * FROM datos where fecha= '"+fech+"' ";
        ResultSet rs = sql.stmt.executeQuery(query);
        rs.first();
        if (rs!=null)
        {
            do
            {
                jTable1.setValueAt(rs.getString("serie"), linea, 0);
                jTable1.setValueAt(rs.getString("placa"), linea, 1);
                jTable1.setValueAt(rs.getString("fecha"), linea, 2);
                jTable1.setValueAt(rs.getString("hora_entrada"), linea, 3);
                jTable1.setValueAt(rs.getString("tipo"), linea, 4);
                jTable1.setValueAt(rs.getString("hora_salida"), linea, 5);
                jTable1.setValueAt(rs.getString("total"), linea, 6);
                linea++;

                if (linea >= 4)
                {
                    agregarnuevafila(jTable1);
                }
                rs.next();
            }while(rs!=null);
        }
    }
    catch(SQLException ex)
    {
        System.out.println(ex);
    }

}

public static void reiniciarJTable(javax.swing.JTable Tabla){
    DefaultTableModel modelo = (DefaultTableModel) Tabla.getModel();
    while(modelo.getRowCount()>0)modelo.removeRow(0);

    TableColumnModel modCol = Tabla.getColumnModel();
    while(modCol.getColumnCount()>0)modCol.removeColumn(modCol.getColumn(0));
}

控制台中的异常显示是这样

最佳答案

DefaultTableModel temp = (DefaultTableModel) Table.getModel();
Object nuevo[] = {"","","","","","",""};

//Inserta la nueva fila al objeto correspondiente
temp.addRow(nuevo);

您的TableModel有0列。创建JTable时，需要指定所需的列数：

DefaultTableModel model = new DefaultTableModel(0, 7);
JTable table = new JTable( model );
