elementUI表格无数据显示图片

<el-table
                                    :data="tableData"
                                    border
                                    empty-text="当前数据没有，请添加数据"
                                    style="width: 100%">
                                <el-table-column
                                        align="center"
                                        prop="date"
                                        label="日期"
                                        width="180">
                                </el-table-column>
                                <el-table-column
                                        align="center"
                                        prop="name"
                                        label="姓名"
                                        width="180">
                                </el-table-column>
                                <el-table-column
                                        align="center"
                                        prop="address"
                                        label="地址">
                                </el-table-column>
                            </el-table>

但是如果想显示动画或者图片呢？下面这样可以嵌入HTML按钮或者图片

<el-table
                                    :data="tableData"
                                    border
                                    empty-text="当前数据没有，请添加数据"
                                    style="width: 100%">
                                <el-table-column
                                        align="center"
                                        prop="date"
                                        label="日期"
                                        width="180">
                                </el-table-column>
                                <el-table-column
                                        align="center"
                                        prop="name"
                                        label="姓名"
                                        width="180">
                                </el-table-column>
                                <el-table-column
                                        align="center"
                                        prop="address"
                                        label="地址">
                                </el-table-column>
                                <div slot="empty">
                                    <p>
                     <el-button size="small" type="primary"> 添加 </el-button>
                        <img src=""/>
                                    </p>
                                </div>
                            </el-table>
