你可以通过设置工具和标题的CSS样式来调整工具的位置。我已经更新了小提琴，检查你分享的小提琴！也有代码供你参考！
CSS代码：

.x-tool-after-title{
    top:auto !important;
}

.x-title-rotate-right{
    top:30px !important;
}

app.js:

Ext.application({
    name: 'Fiddle',

    launch: function() {
        var mainView = new Ext.panel.Panel({
            xtype: 'panel',
            title: 'Container',
            layout: 'border',
            itemId: 'bigContainer',
