Customize table columns in HTML

I want to have a table, so that if the page width decreases, the columns of the table should be displayed one below the other.

You can use CSS display properties to change the way the table behaves. To force table cells to sit on top of one another, you need to create a media query that sets the table and each cell display: block

at the breakpoint that best suits your needs.

In the example below, the table cells will wrap when the screen width is reduced to 500px.

Example

@media (max-width: 500px) {

    table {
        display: block;
        border: solid 1px #f00;
    }
    table td {
        display: block;
        border: solid 1px #f00;
    }
}
      

<table>
    <tr>
        <td>Column 1</td>
        <td>Column 2</td>
    </tr>
</table>
      

Run codeHide result


Explanation



By default, the tag table

uses display: table

and the table cell uses display: table-cell

. By changing these properties, we can change the way the table is displayed.

Ok, if I understand correctly, you want something like this: http://codepen.io/geoffyuen/pen/FCBEg

This solution will help make your table responsive so it can do what you are trying to do (after all, I know what you are trying to do)

Just one example of html code

<h1>RWD List to Table</h1>
<table class="rwd-table">
  <tr>
    <th>Movie Title</th>
    <th>Genre</th>
    <th>Year</th>
    <th>Gross</th>
  </tr>
  <tr>
    <td data-th="Movie Title">Star Wars</td>
    <td data-th="Genre">Adventure, Sci-fi</td>
    <td data-th="Year">1977</td>
    <td data-th="Gross">$460,935,665</td>
  </tr>
  <tr>
    <td data-th="Movie Title">Howard The Duck</td>
    <td data-th="Genre">"Comedy"</td>
    <td data-th="Year">1986</td>
    <td data-th="Gross">$16,295,774</td>
  </tr>
  <tr>
    <td data-th="Movie Title">American Graffiti</td>
    <td data-th="Genre">Comedy, Drama</td>
    <td data-th="Year">1973</td>
    <td data-th="Gross">$115,000,000</td>
  </tr>
</table>

      



Then we have CSS

@import "compass/css3";

// More practical CSS...
// using mobile first method (IE8,7 requires respond.js polyfill https://github.com/scottjehl/Respond)

$breakpoint-alpha: 480px; // adjust to your needs

.rwd-table {
  margin: 1em 0;
  min-width: 300px; // adjust to your needs

  tr {
    border-top: 1px solid #ddd;
    border-bottom: 1px solid #ddd;
  }

  th {
    display: none; // for accessibility, use a visually hidden method here instead! Thanks, reddit!   
  }

  td {
    display: block; 

    &:first-child {
      padding-top: .5em;
    }
    &:last-child {
      padding-bottom: .5em;
    }

    &:before {
      content: attr(data-th)": "; // who knew you could do this? The internet, that who.
      font-weight: bold;

      // optional stuff to make it look nicer
      width: 6.5em; // magic number :( adjust according to your own content
      display: inline-block;
      // end options

      @media (min-width: $breakpoint-alpha) {
        display: none;
      }
    }
  }

  th, td {
    text-align: left;

    @media (min-width: $breakpoint-alpha) {
      display: table-cell;
      padding: .25em .5em;

      &:first-child {
        padding-left: 0;
      }

      &:last-child {
        padding-right: 0;
      }
    }

  }


}


// presentational styling

@import 'http://fonts.googleapis.com/css?family=Montserrat:300,400,700';

body {
  padding: 0 2em;
  font-family: Montserrat, sans-serif;
  -webkit-font-smoothing: antialiased;
  text-rendering: optimizeLegibility;
  color: #444;
  background: #eee;
}

h1 {
  font-weight: normal;
  letter-spacing: -1px;
  color: #34495E;
}

.rwd-table {
  background: #34495E;
  color: #fff;
  border-radius: .4em;
  overflow: hidden;
  tr {
    border-color: lighten(#34495E, 10%);
  }
  th, td {
    margin: .5em 1em;
    @media (min-width: $breakpoint-alpha) { 
      padding: 1em !important; 
    }
  }
  th, td:before {
    color: #dd5;
  }
}

      

Hope this helps you
