我想在树面板的树列中放置一个链接，实际上我可以将我想要的链接放置在该列中，但该链接会显示在另一列中的文件夹和复选框中，我的问题是如何删除该元素并维护该链接

我有以下代码：

这是树面板的视图：

    initComponent: function() {
    var anchoPanatallaRes = window.screen.width;
    var altoPantallaRes = window.screen.height;

    var anchoTOC = 330;
    var altoTOC = 473;

    if (anchoPanatallaRes <= 1024) {
        anchoTOC = 282;
        altoTOC = 373;
    }
    var treeStore = Ext.getStore('capa');

    function addUrl(value, p, record) {
        return value ? Ext.String.format(
                '<a href="'+value+'"target="_blank"'+'>Ver metadato'+'</a>'
        ):'';
    }

    var tree = Ext.create('Ext.tree.Panel', {

                    try {
                        v = new RegExp(field.getValue(), 'i');
                        treeStore.filter({

                                var children = node.childNodes,
                                len = children && children.length,

                                //Visibilidad de los hijos 
                                visible = node.isLeaf() ? v.test(node.get('nombre')) : false,   i;

                                //Visibilidad de los padres
                                for (i = 0; i < len && !(visible = children[i].get('visible')); i++);

                                return visible;
                            },
                            id: 'campoFiltroCapa'
                        });
                    } catch (e) {
                        field.markInvalid('Expresión no valida');
                    }
                },
                buffer: 250
            }
        }]
    });

    Ext.apply(this, {
        title: 'TABLA CONTENIDO',
        id: 'ventanaCapas',
        constrain: true,
        header : {
            titlePosition : 2,
            titleAlign : 'center'
        },
        closable : false,
        width : anchoTOC,

        animCollapse : true,
        collapsible : true,
        collapseDirection : Ext.Component.DIRECTION_LEFT,

            collapse : function(p) {
            }
        },
        items: [tree],
    });
    this.callParent(arguments);
}

商店：

Ext.define('app.store.capa', {
extend: 'Ext.data.TreeStore',
requires: 'app.model.modeloCapa',
model: 'app.model.modeloCapa'
});

只需删除第二个

树列上的xtype

。它将默认为

gridcolumn

，因此它看起来像一个普通的网格列
