//设置el-table宽度 获取table的宽度、设置高度 

<el-table
      :style="{ width: tableWidth }"
      :height="tableHeight"
      :max-height="maxTableHeight"
    >


:style="'width:'+dataWidths+'px'"
this.tableWidth = "64%";
this.tableHeight = this.screenHeight - 260

let dataWidth = this.$refs.element.offsetWidth;//offsetHeight

Vue获取元素高度.

<div ref="element"></div> 

let titles = document.getElementsByClassName("nav-title");
let footer = document.querySelector(".pagefooter").offsetTop;
let divHeight = document.getElementById("div").clientWidth  // clientHeight
//vm.$el获取Vue实例关联的DOM元素；
let scrollview = this.$el.querySelector("#scrollview");

this.$nextTick(() => {
  console.log(this.$refs.element.offsetHight);
})

:style="'width:'+dataWidths+'px'"

let dataWidth = this.$refs.element.offsetWidth;//offsetHeight

    // 获取浏览器可视区域高度
    this.clientWidth = `${document.documentElement.clientWidth}`;
    this.clientHeight = `${document.documentElement.clientHeight}`;
    console.log(this.clientWidth)

// 获取高度值 （内容高+padding+边框）

let height= this.$refs.element.offsetHeight;  //100 offsetWidth

// 获取元素样式值 （存在单位）

let height = window.getComputedStyle(this.$refs.element).height; // 100px width

//获取元素内联样式值（非内联样式无法获取）

let height = this.$refs.element.style.height; // 100px width
