嗨，我正在尝试使用TableRowSorter从Jtable过滤信息，但出现此错误：java.lang.ArrayIndexOutOfBoundsException。
当jframe开始使用LlenarTablaTrue（）时，InicializarCrudCos（）填写表格。
LlenarTablaTrue（）使用jframe中已经创建的jtable，并将其填充（它可以工作）并返回defaulttablemodel。
FiltrarDatos（）用于从LlenarTablaTrue（）获取表模型并设置tablerowsorter。
这是代码（删除了一些未用于创建表或对其进行过滤的代码）：
public CentrocostosCRUD(CentrocostosDAO centrocostosCRUD, PanelLaboral_CentroCostos ventanaCentrocostos) {
this.centrocostosCRUD = centrocostosCRUD;
this.ventanaCentrocostos = ventanaCentrocostos;
this.ventanaCentrocostos.TFbusqueda.addKeyListener(this);
}
public void InicializarCrudCos() {
LlenarTablaTrue(ventanaCentrocostos.TablaCos);
//TablaCos is the name of the jtable in the jframe
}
public DefaultTableModel LlenarTablaTrue(JTable TablaUbi) {
DefaultTableModel modeloT = new DefaultTableModel();
TablaUbi.setModel(modeloT);
TablaUbi.setDefaultEditor(Object.class, null);
modeloT.addColumn("ID");
modeloT.addColumn("Centro de Costos");
modeloT.addColumn("Descripción");
modeloT.addColumn("Estado");
Object[] columna = new Object[4];
int numRegistros = centrocostosCRUD.listarTrue().size();
for (int i = 0; i < numRegistros; i++) {
columna[0] = centrocostosCRUD.listarTrue().get(i).getCos_id();
columna[1] = centrocostosCRUD.listarTrue().get(i).getCos_nombre();
columna[2] = centrocostosCRUD.listarTrue().get(i).getCos_descripcion();
String estado = "Habilitado";
columna[3] = estado;
modeloT.addRow(columna);
}
return modeloT;
}
public void FiltrarDatos(String query) {
DefaultTableModel model = LlenarTablaTrue(ventanaCentrocostos.TablaCos);
TableRowSorter<DefaultTableModel> tr = new TableRowSorter<DefaultTableModel>(model);
ventanaCentrocostos.TablaCos.setRowSorter(tr);
tr.setRowFilter(RowFilter.regexFilter(query));
}
@Override
public void keyTyped(KeyEvent e) {
}
@Override
public void keyPressed(KeyEvent e) {
}
@Override
public void keyReleased(KeyEvent e) {
if (e.getSource() == ventanaCentrocostos.TFbusqueda) {
String query = ventanaCentrocostos.TFbusqueda.getText().toLowerCase();
FiltrarDatos(query);
}
}
在用于搜索的文本框中键入（TFbusqueda）不会执行任何操作。
