ivew table组件二次封装,解决slot-scope跨组件传递的问题

1. 需求

iview Table组件支持自定义列模板

<template>
    <Table :columns="columns" :data="tableData">
        <template slot-scope="{ row }" slot="name">
            <strong>{{ row.name }}</strong>
        </template>
    </Table>
</template>
<script>
    export default {
        data () {
            return {
                columns: [
                    {
                        title: 'Name',
                        slot: 'name'
                    }
                ],
                tableData: [{ name: 'John Brown' }]
            }
        }
    }
</script>

工作中,常常会对Table组件进行二次封装,那么怎么将插槽内容从父组件中传入封装的组件中呢?

2. 解决办法

封装的组件custom-table.vue

<template>
    <Table :columns="columns" :data="tableData">
        <template  v-for="column in columns"  :slot="column.slot?column.slot:''" slot-scope="params" >
			<slot :name="column.slot?column.slot:''" v-bind="params" ></slot>
		</template>
    </Table>
</template>
<script>
    export default {
        props: [columns, tableData]
    }
</script>

在父组件list.vue中使用如下:

<template>
    <custom-table :columns="columns" :tableData="tableData">
        <template slot-scope="params" slot="operater">{{params.row.id}}</template>
    </custom-table>
</template>
<script>
    import CustomTable from "@/components/custom-table";
    export default {
        components: { CustomTable },
        data() {
            return {
                tableData: [{id: 1}],
                columns: [{
                    title: '操作',
                    slot: 'operater'
                }]
            }
        }
    }
</script>

封装后使用方式和原iview Table保持一致。
