前言：项目中有这个需求，然后找到了另外的方法，记录一下
Tinymce 版本5可实现对lineheight的设置
在toolbar中添加属性 styleselect
在初始化init方法中添加：
style_formats: [
{
title: "Line Height",
items: [
{ title: "1", block: "p", styles: { "line-height": "1.0" } },
{ title: "1.5", block: "p", styles: { "line-height": "1.5" } },
{ title: "1.75", block: "p", styles: { "line-height": "1.75" } },
{ title: "2", block: "p", styles: { "line-height": "2" } },
{ title: "3", block: "p", styles: { "line-height": "3" } },
{ title: "4", block: "p", styles: { "line-height": "4" } },
{ title: "5", block: "p", styles: { "line-height": "5" } }
]
}
],
style_formats_merge: true, //设置行高
style_formats_autohide: true //设置行高
如图：
