最近用到 element-ui 的 el-form，要求一行里面放置多个 el-form-item。

其实很简单，用 layout 布局就可以简单实现。

layout 布局是通过基础的24分栏，从而迅速简洁地创建布局。

代码实现如下：

<el-form size="mini"
         label-width="160px"
         label-position="right"
         :model="formData"
         :ref="FormName"
         :rules="rules">
      <el-row>
        <el-col :span="12">
          <el-form-item prop="sbbh"
                        :label="$t('deviceManage.device.table.sbbh')+':'">
            <el-input v-model="formData.sbbh"
                      :placeholder="$t('deviceManage.device.dlg.sbbh')" />
          </el-form-item>
        </el-col>
        <el-col :span="12">
          <el-form-item prop="name"
                        :label="$t('deviceManage.device.table.name')+':'">
            <el-input v-model="formData.name"
                      :placeholder="$t('deviceManage.device.dlg.name')" />
          </el-form-item>
        </el-col>
      </el-row>
      <el-row>
        <el-col :span="12">
          <el-form-item prop="deptId"
                        :label="$t('deviceManage.device.table.deptId')+':'">
            <treeselect :options="deptTree"
                        :normalizer="normalizer"
                        v-model="formData.deptId"
                        :placeholder="$t('deviceManage.device.dlg.deptId')">
            </treeselect>
          </el-form-item>
        </el-col>
        <el-col :span="12">
          <el-form-item prop="staffId"
                        :label="$t('deviceManage.device.table.staffId')+':'">
            <el-select v-model="formData.staffId"
                       :placeholder="$t('deviceManage.device.dlg.staffId')">
              <el-option v-for="(item,i) in staffOption"
                         :key="i"
                         :label="item.label"
                         :value="item.value">
              </el-option>
            </el-select>
          </el-form-item>
        </el-col>
      </el-row>
</el-form>

页面效果如下：
