                 })}
          </tr>
      ) 
 })}

Answer 1

您应该使用外部地图的index并且由于索引以0开头，因此您应该根据需要添加 1：

<td> {index+1} </td> 

Answer 2

Try this

this.props.data.map((row, index) => (
    <tr key={index}>
        <td> {index + 1} </td>
        {row.map((col, colIndex) => (
            <td key={colIndex}> {col.fullname} </td>
        ))}
    </tr>
));
