Ant-design表格添加索引列

博客介绍了分页索引的两种情况,一是每一页索引都从1开始,二是有分页且索引连续自增。

分为两种情况:
1、每一页索引都从1开始

<a-table :colums="colums"></a-table>
//配置表格的columns:
...
colums: [
    {
        title: '排名',
        customRender:(text,record,index) => index + 1
    },
    {
        title: '姓名',
        dataIndex:'uname'
    },
    {
        title: '分数',
        dataIndex:'score'
    }
    //...
]

2、有分页情况且连续自增

<a-table :colums="colums" :pagination="pagination"></a-table>

data() {
    return {
        pagination:
        {
            total: 0,
            defaultCurrent: 1,
            defaultPageSize: 10,
            showTotal: (total) => `共${total}条数据`,
            showSizeChanger: true,
            pageSizeOptions: ['5', '10', '15', '20'],
            onShowSizeChange: (current, pageSize) => {
              // this.pageSize = pageSize;
              this.pagination.defaultCurrent = current;
              this.pagination.defaultPageSize = pageSize;
            },
            onChange: (current, pageSize) => {
              // this.pageSize = pageSize;
              this.pagination.defaultCurrent = current;
              this.pagination.defaultPageSize = pageSize;
            },
          }},
        colums: [
            {
                title: '排名',
                customRender:(text,record,index) => 
                this.pagination ? `${(this.pagination.defaultCurrent-1)*(thi.pagination.defaultPageSize)+index+1}` :index+1
            },
            {
                title: '姓名',
                dataIndex:'uname'
            },
            {
                title: '分数',
                dataIndex:'score'
            }
            //...
        ],
        
    }
};


如果你想在Ant-Design-Vue表格中设置单元格的背景色,可以使用`customRender`属性来自定义单元格的渲染方式,具体可以参考以下代码: ```html <template> <a-table :columns="columns" :data-source="data"> <template slot="name" slot-scope="text, record"> <span :style="{backgroundColor: record.color}">{{text}}</span> </template> </a-table> </template> <script> export default { data() { return { columns: [ { title: "Name", dataIndex: "name", key: "name", customRender: (text, record, index) => { if (index > 2) { return <span :style="{backgroundColor: record.color}">{text}</span>; } else { return text; } }, }, { title: "Age", dataIndex: "age", key: "age", }, { title: "Address", dataIndex: "address", key: "address", }, ], data: [ { key: 1, name: "John Brown", age: 32, address: "New York No. 1 Lake Park", color: "#f0f0f0", }, { key: 2, name: "Jim Green", age: 42, address: "London No. 1 Lake Park", color: "#f0f0f0", }, { key: 3, name: "Joe Black", age: 32, address: "Sidney No. 1 Lake Park", color: "#f0f0f0", }, { key: 4, name: "Jim Red", age: 32, address: "London No. 2 Lake Park", color: "#f0f0f0", }, { key: 5, name: "Jake White", age: 32, address: "Dublin No. 2 Lake Park", color: "#f0f0f0", }, ], }; }, }; </script> ``` 在上述代码中,我们通过`customRender`方法来自定义单元格的渲染方式,并且在前三不设置单元格的背景色。具体实现中,我们在`customRender`方法中判断当前单元格的索引是否大于2,如果是,则渲染带有背景色的`span`标签,否则直接返回文本。同时,我们在模板中使用`slot`以及`slot-scope`属性来渲染自定义单元格。
