React Bootstrap: Vertical alignment of row's columns?

You can apply any of Bootstrap's classes to a React Bootstrap component. So, per the Grid System docs, the following columns will both be centered vertically:

<Row className="align-items-center">
  <Col>
    <h1>{title}</h1>
    <p>{details}</p>
  </Col>
  <Col>
    <button>{callToAction}</button>
  </Col>
</Row>;

If you are using table rows, you can wrap contents within a <div>..</div>

like:

<tr>
  <div classname="align-me"></div>
</tr>

and then you can use flexbox to align them dynamically:

tr .align-me {
  display: flex;
  align-items: center;
}
