如何调整extjs组合框的宽度

Question

我有一个面板，它有几个组合框和按钮。第一个组合框与左侧对齐。我希望将其与下面的那些类似。该按钮也应该与组合相邻。 请帮忙。以下是代码

filterPanel = new Ext.Panel({
        renderTo: document.body,
        bodyStyle: 'padding-top: 6px;',
        title: 'Filters',
        collapsible: true,
        collapsed: true,
        width: 450,
        frame: true,
        floating: true,
        layout: 'form',
        labelWidth: 150,
        buttonAlign: 'center',

        items: [
            {
                layout:'column',
                items:[
                {
                    columnWidth:.9 ,
                    layout: 'form',
                    items: [{
                        xtype:'combo',
                        id: 'xFilterEmail',
                        width: 250,
                        listWidth: 200,

                        selectOnFocus:false

嗯......第一个组合框的宽度为250.你试着让它等于其他组合（200）吗？如果您无法将按钮移动到左侧，我会用CSS代替。 如果你给按钮一个ID“myButton”，下面的CSS应该可以解决这个问题：

#myButton .x-btn {
    margin-left:-20px !important;
}

并且不要害怕编辑ExtJS类，因为它只会对此按钮进行更改。我一直这样做，结果如预期。
