vue-quill-editor 注冊行高樣式

lineHeight.js：

import Quill from "quill";
let Parchment = Quill.import("parchment");
console.log(Parchment);
class lineHeightAttributor extends Parchment.Attributor.Style {}
const lineHeightStyle = new lineHeightAttributor("lineHeight", "line-height", {
  scope: Parchment.Scope.INLINE,
  whitelist: ["initial", "1", "1.5", "1.75", "2", "3", "4"]
});

export { lineHeightStyle };

使用時引入 

import { lineHeightStyle } from "@/utils/lineheight";

quillEditor 組件 ready 事件中調用：（更詳細的在上一節）

 <quill-editor  
        @ready="ready($event)"
    >
    </quill-editor>    

ready：

 ready() {
      Quill.register({ "formats/lineHeight": lineHeightStyle }, true);
    },
