问如何使用带有自定义Quill工具栏的默认字体大小选择器？

EN

const toolbarOptions = [
    [
        { font: ['Lato,sans-serif'] },
    ],
    [{ 'size': ['small', false, 'large', 'huge'] }],

    ['bold', 'italic', 'underline'],
    ['link'],
    ['clean'],
];

const quill = new Quill('#editor', {
    theme: 'snow',
    modules: {
        toolbar: toolbarOptions
    }
});
