<el-date-picker v-model="weekValue" type="week" format="yyyy 第 WW 周" placeholder="选择周" :picker-options="pickerOptions" @change="weekChange"
pickerOptions: { firstDayOfWeek: 3, },
please change month to Feb in any year , and choose week includes 2rd Feb or next week, you will see the value of weekValue and chosen line in page doesn't match
/packages/date-picker/src/basic/date-table.vue文件中，handleClick事件，当firstDayOfWeek改变时，时间选择table的页面是不同的，并且401行，如果是week，column直接等于1，这样得到点击的日期值是错误的，进而根据日期计算出的周的时间也是错误的
Can YOU give me a firstDayOfWeek configuration
