el-date-picker日期选择限制范围

1.如果只比较两个值的话—效果是这种的

// 这是<template>的
 <el-row>
            <el-col :span="12">
              <el-form-item label="计划评审日期(起)" prop="planPsDateStart">
                <el-date-picker
                  v-model="vm.edit.data.planPsDateStart"
                  type="date"
                  :picker-options="pickerOption_start"
                  placeholder="开始时间"
                  style="width: 100%"
                />
              </el-form-item>
            </el-col>
            <el-col :span="12">
              <el-form-item label="计划评审日期(止)" prop="planPsDateEnd">
                <el-date-picker
                  v-model="vm.edit.data.planPsDateEnd"
                  type="date"
                  :picker-options="pickerOption_end"
                  placeholder="结束时间"
                  style="width: 100%"
                />
              </el-form-item>
            </el-col>

          </el-row>



// 这是<script>下的data的
  pickerOption_start: {
        disabledDate: (time) => {
          if (this.vm.edit.data.planPsDateEnd !== undefined) {
            return time.getTime() > this.vm.edit.data.planPsDateEnd
          }
        }
      },
      pickerOption_end: {
        disabledDate: (time) => {
          if (this.vm.edit.data.planPsDateStart !== undefined) {
            return time.getTime() < this.vm.edit.data.planPsDateStart
          }
        }
      }

2.如果是table一直在循环这种日期，而且只比较每一行的两个日期

效果是这样的

// 放在el-table下的两列
<el-table-column prop="lastModifyUserId" label="计划开始日期" align="center">
              <template slot-scope="scope">
                <el-date-picker
                  v-model="scope.row.planStart"
                  type="date"
                  placeholder="计划开始日期"
                  :picker-options="{disabledDate: (time) => {if (scope.row.planEnd !== undefined) {return time.getTime() > scope.row.planEnd} }}"
                  style="width: 100%"
                  :disabled="limitsDisabledFun()"
                />
              </template>
            </el-table-column>
            <el-table-column prop="name" label="计划结束日期" align="center">
              <template slot-scope="scope">
                <el-date-picker
                  v-model="scope.row.planEnd"
                  type="date"
                  placeholder="计划结束日期"
                  :picker-options="{disabledDate: (time) => {if (scope.row.planStart !== undefined) {return time.getTime() < scope.row.planStart} }}"
                  style="width: 100%"
                  :disabled="limitsDisabledFun()"
                />
              </template>
            </el-table-column>

 原理一样的-就是把data下的pickerOption直接嵌到代码里面，不放在data中
