ElementUI表格如何获取当前行的数据？

话不多说，先上ElementUI的部分表格html代码：

                    <el-table
                                ref="multipleTable"
                                :data="musics"
                                tooltip-effect="dark"
                            >
                            <el-table-column
                                    type="selection"
                                    width="45">
                            el-table-column>
                            <el-table-column
                                    label="编号"
                                    width="50"
                                    prop="musicId">
                            el-table-column>
                            <el-table-column
                                    label="歌曲名字"
                                    width="auto"
                                    prop="musicName">
                            el-table-column>
                            <el-table-column
                                    prop="musicAlbumName"
                                    label="专辑名字"
                                    width="auto"
                            >
                            el-table-column>
                            <el-table-column
                                    prop="musicMp3Url"
                                    label="歌曲URL"
                                    show-overflow-tooltip>
                            el-table-column>
                            <el-table-column
                                    prop="musicAlbumPicUrl"
                                    label="专辑URL"
                                    show-overflow-tooltip>
                            el-table-column>
                            <el-table-column
                                    prop="musicArtistName"
                                    label="歌手"
                                    show-overflow-tooltip>
                            el-table-column>
                            <el-table-column
                                prop="date"
                                label="创建日期"
                                :formatter="dateSwitch"
                                width="auto"
                            >
                            el-table-column>
                            <el-table-column
                                    label="操作"
                                    show-overflow-tooltip>
                                <template slot-scope="scope">
                                        <el-button type="primary" size="min" plain @click="edit(scope.row)">编辑el-button>
                                        <el-button type="danger" size="min"  plain @click="del(scope.row.musicId)">删除el-button>
                                template>
                            el-table-column>
                        el-table>

假如这时候表格中的数据是已经显示过的，要想拿到当前表格中指定行数的数据时，则需要在
template标签中添加这个属性即可      slot-scope=“scope”     同时写出一个点击事件的方法例如上述的编辑按钮
其中 scope.row就是拿到当前行的所有数据，如果要想拿到制定数据，则需要指定你当前行指定需要的数据的字段就好，如：scope.row.musicId
