当编辑器里的内容为

| 序号 | 其他其他 |
| ---- | -------- |
| 1    |          |
| 2    |          |
| 3    |          |
| 4    |          |

的时候，api方法 getMarkdown()会报错，提示此处c为null

这种方式就可以☺

setContent(content: string) { // this.focus().clear().insert(content); this.focus().clear().innerEditor.commands.setContent(content); return this; }
