This front-end framework, along with plenty of other features , provides a variety of features for designing and improving the display of different elements, such as tables.
To style a table  using Bootstrap,  just simply add the table class to the <table> tag, and  a number of  graphic  format will  actually be applied , as  displayed on the screenshot .

<table class="table">
  <thead>
    <tr>
      <th>#</th>
      <th>First Name</th>
      <th>Last Name</th>
      <th>Username</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">1</th>
      <td>Mark</td>
      <td>Otto</td>
      <td>@mdo</td>
    </tr>
    <tr>
      <th scope="row">2</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>
      <th scope="row">3</th>
      <td>Larry</td>
      <td>the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>One of the  latest tables in Bootsrap 4 is the inverse tables. Class .table-inverse  is able to change the  colors of the table.

<table class="table table-inverse">
  <thead>
    <tr>
      <th>#</th>
      <th>First Name</th>
      <th>Last Name</th>
      <th>Username</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">1</th>
      <td>Mark</td>
      <td>Otto</td>
      <td>@mdo</td>
    </tr>
    <tr>
      <th scope="row">2</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>
      <th scope="row">3</th>
      <td>Larry</td>
      <td>the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>For tables there are also some classes that allow you to add other styles to a table, they are:
● table-striped Toggles the  color tone of table rows;
● table-bordered Adds border to table;
● table-hover  Switches on the highlight of a Bootstrap Tables Twitter line when we hover the mouse cursor over it;
● table-condensed Reduces the height of table rows, making it more compact.
To add all of these styles, just simply add the chosen classes to the: <table>: <table class="table table-striped table-bordered table-condensed table-hover">
Like default and inverse tables,  put into action one of two modifier classes to make <thead>  show up  light or dark  gray.

      <td>the Bird</td>
      <td>@twitter</td>

</table>Zebra-like stripes can be  brought with the .table-striped class, an  good example

<table class="table table-striped">
  <thead>
    <tr>
      <th>#</th>
      <th>First Name</th>
      <th>Last Name</th>
      <th>Username</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">1</th>
      <td>Mark</td>
      <td>Otto</td>
      <td>@mdo</td>
    </tr>
    <tr>
      <th scope="row">2</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>
      <th scope="row">3</th>
      <td>Larry</td>
      <td>the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>To generate a hover effect in the rows of your table  bring in the .table-hover class:

<table class="table table-hover">
  <thead>
    <tr>
      <th>#</th>
      <th>First Name</th>
      <th>Last Name</th>
      <th>Username</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">1</th>
      <td>Mark</td>
      <td>Otto</td>
      <td>@mdo</td>
    </tr>
    <tr>
      <th scope="row">2</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>
      <th scope="row">3</th>
      <td colspan="2">Larry the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>You  can surely  incorporate the borders on each table slide and a cell  using the .table-bordered class:

<table class="table table-bordered">
  <thead>
    <tr>
      <th>#</th>
      <th>First Name</th>
      <th>Last Name</th>
      <th>Username</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">1</th>
      <td>Mark</td>
      <td>Otto</td>
      <td>@mdo</td>
    </tr>
    <tr>
      <th scope="row">2</th>
      <td>Mark</td>
      <td>Otto</td>
      <td>@TwBootstrap</td>
    </tr>
    <tr>
      <th scope="row">3</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>
      <th scope="row">4</th>
      <td colspan="2">Larry the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>Wherever you  like to make your table more  small - then you  can easily cut cell padding in half  through this class: .table-condensed.
Bear in mind that, while Bootstrap 4 uses .table-sm to condense a table, Bootstrap 3 uses .table-condensed. Both cut cell padding in half.

<table class="table table-sm">
  <thead>
    <tr>
      <th>#</th>
      <th>First Name</th>
      <th>Last Name</th>
      <th>Username</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">1</th>
      <td>Mark</td>
      <td>Otto</td>
      <td>@mdo</td>
    </tr>
    <tr>
      <th scope="row">2</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>
      <th scope="row">3</th>
      <td colspan="2">Larry the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>Use the contextual classes to color a table cells (<td>) and table rows (<tr>):

<!-- On rows -->
<tr class="table-active">...</tr>
<tr class="table-success">...</tr>
<tr class="table-warning">...</tr>
<tr class="table-danger">...</tr>
<tr class="table-info">...</tr>
<!-- On cells (`td` or `th`) -->
<tr>
  <td class="table-active">...</td>
  <td class="table-success">...</td>
  <td class="table-warning">...</td>
  <td class="table-danger">...</td>
  <td class="table-info">...</td>
</tr>Changing the rows of a table Bootstrap 3 doesn't use the .table- prefix for its contextual classes. Bootstrap 3 uses .active whereas Bootstrap 4 uses .table-active.
● active: Uses the focus color option to the table row or table cell
● success: Signifies a successful or positive action
● info: Signifies a neutral information change or action
● warning: Signifies a caution that you may need attention
● danger: Signifies a dangerous or potentially negative action
To create a responsive table - use the .table-responsive class. Table scrolls in the horizontal direction on devices that under 768px. If the device is larger than 768px wide, then you will see no difference :

Bootstrap 4 allows you to add the .table-responsive class to the actual <table> element. Bootstrap 3 tables required that you add that class to a parent <div> element.
