When two data sources are cross-displayed on the page, the page is not tidy

there are two data sources A, B.
on the page with four columns in a row (one piece of data is a Card, row and four Card), such as: A1, B1, A2, B2.
is as follows: dataSource= {data}, data is the data source of An and B together, item= {A1, B1},
but there are some problems. Can you give me some suggestions?

<div style={{ padding: 5 }}>
    <Row gutter={10}>
        <Col span={20}>    
              <List
                 rowKey="id"
                 loading={loading}
                 grid={{ gutter: 10, column: 4}}
                 dataSource={data}
                 renderItem={item =>
                (
                    <div style={{display: "inline"}}>
                        <List.Item>
                              <Card hoverable style={{ fontSize: 14, }} type={ "inner" } title={""}>
                                  <font style={{fontSize:"20", color:"-sharp000", paddingLeft: 25}}>{[item[0].symbol,"(", item[0].cn_name,")"]}</font><br/>
                                  <font style={{fontSize:"20", color:"-sharp000", paddingLeft: 25}}>{item[0].expiry}</font>
                            </Card>
                        </List.Item>,
                           <List.Item>
                            <Card hoverable style={{ fontSize: 14}} type={ "inner" } title={""} extra={<Switch defaultChecked onChange={this.onChange(item.symbol)}/>}>
                                  <font style={{fontSize:"20", color:"-sharp000", paddingLeft: 25}}>{[item[1].symbol,"(", item[1].cn_name,")"]}</font><br/>
                                  <font style={{fontSize:"20", color:"-sharp000", paddingLeft: 25}}>{item[1].expiry}</font>
                            </Card>
                        </List.Item>
                    </div>
                )
                }
            />
        </Col>
        
    </Row>        
</div>
The

page is shown as follows. Why is the Card behind it not aligned with the previous Card? please give us some suggestions on how to modify it:

I don't know what you use to render the data. You can process the data first, organize the An and B data into a new data source, and then render it.
you should be using the iView, style problem. You can debug it with the browser. You can't see what's wrong with the structural code.


is as follows: dataSource= {data}, data is the data source of An and B, item= {A1, B1},
but there are some problems in the display, can you give me some suggestions:
remove the block display of

and you can

<div style={{ padding: 5 }}>
    <Row gutter={10}>
        <Col span={20}>

                 dataSource={data}
