我如何将类别文本对齐配置为居中？

这是 Category Banners 组件。嗯，我刚测试了一下，它对我来说工作正常。看起来你可能有一些其他的 CSS 导致了这个问题……

My category name is aligned to the left, how to center it?

Sounds like you have another component or some css code that is aligning it to the left. The default is the center, which is why it is centred when you preview it from the component. I would remove some of the other theme components that might be conflicting with it until you find the culprit, then you may have to make some code changes or something to fix it.
