Container, Row, Col - in React-Bootstrap not working

Question

I'm currently attempting to learn React, and React-Bootstrap.

I'm attempting to make good use of the React-Bootstrap grid layout. I'm not sure if I'm implementing it incorrectly. My gut says I'm using an impropver version somewhere because as far as I can tell the "Container, Col, Row" functionality isn't working at all.

What could be the issue? I'm out of ideas.

Versions from package.json:

  "dependencies": {
    "bootstrap": "^4.3.1",
    "jquery": "^3.0.0",
    "react": "^16.8.4",
    "react-bootstrap": "^1.0.0-beta.6",
    "react-dom": "^16.8.4",
    "react-scripts": "2.1.8",
    "typescript": "^3.3.4000"

The package.json from "bootstrap" dir:

  "_from": "bootstrap@latest",
  "_id": "[email protected]",

The package.json from "react-bootstrap" dir:

  "_from": "react-bootstrap@^1.0.0-beta.6",
  "_id": "[email protected]",

Please note that I've also tried installing and using bootstrap@3 with no luck:

npm install bootstrap@3 --save npm i --save bootstrap@3

Major snippet from index.js:

import React from 'react';
import ReactDOM from 'react-dom';
import Container from 'react-bootstrap/Container';
import Row from 'react-bootstrap/Row';
import Col from 'react-bootstrap/Col';

class Module extends React.Component
{
  constructor(props)
  {
    super(props);
  }

  clickHandler = (command) =>
  {
    // ... some handler code here
  }

  render()
  {
    return (
      <Container>
        <Row>
          <Col>
            <table>
              <tr>
                <th class="r1_header"> Header 1 </th>
                <th class="r1_header"> Header 2 </th>
                <th class="r1_header"> Header 3 </th>
              </tr>
              <tr>
                <td> <button/> </td> // some more button stuff here
                <td> <button/> </td>
                <td> <button/> </td>
              </tr>
              <tr>
                <td> <button/> </td>
                <td> <button/> </td>
                <td> <button/> </td>
              </tr>
              <tr>
                <td> <button/> </td>
                <td> <button/> </td> 
                <td> <button/> </td>
              </tr>
              <tr>
                <th class="r2_header"> Header 1 </th>
                <th class="r2_header"> Header 2 </th>
                <th class="r2_header"> Header 3 </th>
              </tr>
              <tr>
                <td> <button/> </td>
                <td> <button/> </td>
                <td> <button/> </td>
              </tr>
              <tr>
                <td> <button/> </td>
                <td> <button/> </td>
                <td> <button/> </td>
              </tr>
              <tr>
                <td> <button/> </td>
                <td> <button/> </td>
                <td> <button/> </td>
              </tr>
            </table>
          </Col>
          <Col>
            // another table here... should be aligned next to the
            // prev "col" horizontally but is going underneath (vertically)
          </Col>
        </Row>
      </Container>
    );
  }
}

The displayed text should be HelloWorld but instead its:

I've resolved the issue. It was a miss-step on my part. I missed a crucial part of the set up outlined on the react-bootstrap main regarding style sheets.

In index.html copy and paste the path to the latest bootstrap style sheets:

<link
  rel="stylesheet"
  href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css"
  integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T"
  crossorigin="anonymous"
/>

According to react documentation you have to install bootstrap first

npm Install react-bootstrap bootstrap

then you have to import this line in your index.js or App.js

import 'bootstrap/dist/css/bootstrap.min.css';

then you can import like this in your components import { Container, Row, Col } from 'react-bootstrap'; and use like this

 <Container>
                <Row>
                    <Col>1</Col>
                    <Col>2</Col>
                    <Col>3</Col>
                </Row>
            </Container>
