[yairEO]

• [✓] I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

fixed, styled, table header row for added new table records

What does the proposed API look like?

see my question: https://stackoverflow.com/q/56619026/104380

<Table dataSource={data}>
    <HeaderRow>
        <Column><input /></Column>
        <Column><input type='number' /></Column>
        <Column><select>...</select></Column>
    </HeaderRow>
    <Column title="Person's name" dataIndex="name" key="name" render={item => <strong>{item}</strong>} />
    <Column title="Person's age" dataIndex="age" key="age" />
    <Column title="gender" dataIndex="gender" key="gender" />
</Table>

Expected result should look like:
