不用修改下载的源文件，直接在editorquill.vue文件中修改即可

重点部分如下

1. [{ size: [’10px’, ’12px’, false, ’16px’, ’18px’, ’20px’, ’30px’, ’32px’] }], // 字体大小
2. [{ font: [false, ‘SimSun’, ‘SimHei’, ‘Microsoft-YaHei’, ‘KaiTi’, ‘FangSong’, ‘Arial’, ‘sans-serif’] }], // 字体种类

3. import { Quill,quillEditor } from “vue-quill-editor”;   正常没有引入红色，需额外引入红色并添加 4 

4. // 自定义字体大小

     let Size = Quill.import(‘attributors/style/size’)

     Size.whitelist = [’10px’, ’12px’, ’16px’, ’18px’, ’20px’, ’30px’, ’32px’]

     Quill.register(Size, true)

     // 自定义字体类型

     var fonts = [‘SimSun’, ‘SimHei’, ‘Microsoft-YaHei’, ‘KaiTi’, ‘FangSong’, ‘Arial’, ‘sans-serif’]

     var Font = Quill.import(‘formats/font’)

     Font.whitelist = fonts

     Quill.register(Font, true)

5. 整个style复制替换你自己的

 ps:如有新增的样式或px可依葫芦画瓢依次增加
