Question

虽然ExtJs GridPanel是丰富的datacontrol，但它限制了列冻结功能。只有第一列可以通过锁定属性冻结。有人解决了这个问题吗？

这是我的代码：

Ext.require(['Ext.grid.*', 'Ext.data.*', 'Ext.util.*', 'Ext.state.*']);
Ext.onReady(function () {
    // sample static data for the store
    var myData = [
        ['3m Co', 71.72, 0.02, 0.03, '9/1 12:00am'],

我不同意：

当您锁定列时，它会将列移动到最左侧并将其与其他锁定列堆叠。如果它不这样做那么从用户体验的角度来看整个滚动交互将不起作用。
