How can I make my table height smaller in bootstrap 4?

Question

How can I make my table height smaller? I've tried adjusting the height on the <tr> through CSS but it seems like the height it's currently using is the smallest it will get. I can make it larger but anything under height: 50px, I don't notice a difference.

Here's my table now. I just want to make the row height smaller to compress the table so it fits on the screen without having to scroll down.

    <table class="table table-striped">
            <thead>
              <tr>
                <th scope="col">Month</th>
                <th scope="col">Overtime Hours</th>
                <th scope="col">Compensation Hours</th>
                <th scope="col">Vacation</th>
                <th scope="col">Personal Hours</th>
                <th scope="col">Sick Hours</th>
              </tr>
            </thead>
            <tbody>
              <tr>
                <th scope="row">Carry Over</th>
                <td></td>
                <td></td>
                <td></td>
                <td></td>
                <td></td>
              </tr>
              <tr>

Answer 1

Accordingly to the Bootstrap docs:

You can simply use table-sm as a complement for your table, to make tables more compact by cutting cell padding in half. It would be like:

<table class="table table-striped table-sm">
  <thead>
...
  </thead>
  <tbody>
    <tr>
   ...
    </tr>
  </tbody>
</table>

As recommended to be responsive, you can use .table-responsive{-sm|-md|-lg|-xl} as needed to create responsive tables up to a particular breakpoint. From that breakpoint and up, the table will behave normally and not scroll horizontally.

Example:

<div class="table-responsive-sm">
  <table class="table table-striped">
    ...
  </table>
</div>

<div class="table-responsive-md">
  <table class="table table-striped">
    ...
  </table>
</div>

<div class="table-responsive-lg">
  <table class="table table-striped">
    ...
  </table>
</div>

<div class="table-responsive-xl">
  <table class="table table-striped">
    ...
  </table>
</div>

Answer 2

as you are using bootstrap. you may use <table class="table table-striped table-sm"> class
