本文仅供参考:
首先你要掌握的基础知识:

row 行概念

<el-row></el-row>

col 列概念

<el-col></el-col>

col组件的:span属性的布局调整,一共分为24栏:

代码示例:

    <el-row>
      <el-col :span="24"><div class="grid-content"></div></el-col>
    </el-row>           

效果展示:

代码示例:

    <el-row>
      <el-col :span="12"><div class="grid-content"></div></el-col>
    </el-row>

效果展示:

row组件的:gutter属性来调整布局之间的宽度---分栏间隔

代码示例:

    <el-row :gutter="20">
      <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
      <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
    </el-row>

 

效果:


 

Col组件的:offset属性调整方块的偏移位置(每次1格/24格)

 

    <el-row :gutter="20">
      <el-col :span="6" :offset="6"><div class="grid-content"></div></el-col>
      <el-col :span="6" :offset="6"><div class="grid-content"></div></el-col>
    </el-row>

 

效果:


 

对齐方式:

row组件的type="flex"启动flex布局,再通过row组件的justify属性调整排版方式,属性值分别有:

 

    justify=center 居中对齐
    justify=start 左对齐
    justify=end 右对齐
    justify=space-between 空格间距在中间对齐
    justify=space-around 左右各占半格空格对齐

     <el-row type="flex" class="row-bg" justify="center">
       <el-col :span="6"><div class="grid-content"></div></el-col>
     </el-row>



效果:


 

响应式布局:

参考bootstrap的响应式,预设四个尺寸

    xs <768px
    sm ≥768px
    md ≥992
    lg ≥120

使用方式:

    <el-row :gutter="10">
      <el-col :xs="8" :sm="6" :md="4" :lg="3"><div class="grid-content bg-purple"></div></el-col>
      <el-col :xs="4" :sm="6" :md="8" :lg="9"><div class="grid-content bg-purple-light"></div></el-col>
      <el-col :xs="4" :sm="6" :md="8" :lg="9"><div class="grid-content bg-purple"></div></el-col>
      <el-col :xs="8" :sm="6" :md="4" :lg="3"><div class="grid-content bg-purple-light"></div></el-col>
    </el-row>

 

练习示例:

 

            <span class="field-label">方块选择:</span>
            <!-- 选择屏幕框 -->
              <select v-model="selected" @change="selectbj(selected)">
                <option v-for="option in layouts" :value="option.value">
                    {{ option.name }}
                </option>
              </select>

 

data默认初始化数据:

          selected: 0,
          layouts: [
            { 'name': '1x1模式', 'value': '0' },
            { 'name': '2x1模式', 'value': '1' },
            { 'name': '2x2模式', 'value': '2' },
            { 'name': '3x2模式', 'value': '3' },
            { 'name': '3x3模式', 'value': '4' },
            { 'name': '1+5模式', 'value': '5' }
          ],

 

布局代码:

        <el-main v-model="selected" >
          <div class="block" style="height:400px">
                <!-- {{selected}} -->
                <div style="height:100%;width:100%" v-if="selected==0">
                <!-- 1*1布局 -->
                    <el-row :gutter="10" type="flex" class="grid-one-contentheight" justify="center">
                      <el-col :span="24"></el-col>
                    </el-row>
                </div>
                <!-- 2*1布局 -->
                <div style="height:100%;width:100%" v-else-if="selected==1">
                    <el-row :gutter="10" type="flex" class="row-bg el-row-two" justify="space-between">
                      <el-col :span="12"><div class="grid-content "></div></el-col>
                      <el-col :span="12"><div class="grid-content "></div></el-col>
                    </el-row>
                </div>
                <!-- 2*2 -->
                <div style="height:100%;width:100%" v-else-if="selected==2">
                  <el-row :gutter="10" type="flex" class="row-bg" justify="center">

                      <el-col :span="12"><div class="grid-content "></div></el-col>
                    </el-row>
                </div>
                <!-- 3*2布局 -->
