such as headings,
I want to sort the form by dragging within el-dialog.
can be dragged if it is placed on the general surface.
indicates that I have correctly introduced sortablejs into
, but if I put the form on el-dialog,
drag sorting will become invalid.
from the console point of view,
I am sure to select the correct form,
but still can not solve the problem,
ask for a high point of reference.

<template>
    <div>
        <el-button @click="dialogFormVisible = true"></el-button>


        <el-dialog  :visible.sync="dialogFormVisible">
            <el-table row-key="date" ref="table" border :data="tableData" style="width: 100%" id="AA">
                <el-table-column prop="date" label="" width="180">
                </el-table-column>
                <el-table-column prop="name" label="" width="180">
                </el-table-column>
                <el-table-column prop="address" label="">
                </el-table-column>
            </el-table>
        </el-dialog>
    </div>
