How can I make a CSS table fit the screen width?

Question

Currently the table is too wide and causes the browser to add a horizontal scroll bar.

Solution 1

If the table content is too wide (as in this example), there's nothing you can do other than alter the content to make it possible for the browser to show it in a more narrow format. Contrary to the earlier answers, setting width to 100% will have absolutely no effect if the content is too wide (as that link, and this one, demonstrate). Browsers already try to keep tables within the left and right margins if they can, and only resort to a horizontal scrollbar if they can't.

Some ways you can alter content to make a table more narrow:

• Reduce the number of columns (perhaps breaking one megalithic table into multiple independent tables).
• If you're using CSS white-space: nowrap on any of the content (or the old nowrap attribute,  , a nobr element, etc.), see if you can live without them so the browser has the option of wrapping that content to keep the width down.
• If you're using really wide margins, padding, borders, etc., try reducing their size (but I'm sure you thought of that).

If the table is too wide but you don't see a good reason for it (the content isn't that wide, etc.), you'll have to provide more information about how you're styling the table, the surrounding elements, etc. Again, by default the browser will avoid the scrollbar if it can.

Solution 2

CSS:

table { 
    table-layout:fixed;
}

Update with CSS from the comments:

td { 
    overflow: hidden; 
    text-overflow: ellipsis; 
    word-wrap: break-word;
}

For mobile phones I leave the table width but assign an additional CSS class to the table to enable horizontal scrolling (table will not go over the mobile screen anymore):

@media only screen and (max-width: 480px) {
    /* horizontal scrollbar for tables if mobile screen */
    .tablemobile {
        overflow-x: auto;
        display: block;
    }
}

Sufficient enough.

Solution 3

table { width: 100%; }

Will not produce the exact result you are expecting, because of all the margins and paddings used in body. So IF scripts are OKAY, then use Jquery.

$("#tableid").width($(window).width());

If not, use this snippet

<style>
    body { margin:0;padding:0; }
</style>
<table width="100%" border="1">
    <tr>
        <td>Just a Test
        </td>
    </tr>
</table>

You will notice that the width is perfectly covering the page.

The main thing is too nullify the margin and padding as I have shown at the body, then you are set.

Solution 4

Put the table in a container element that has

overflow:scroll; max-width:95vw;

or make the table fit to the screen and overflow:scroll all table cells.

Solution 5

Instead of using the % unit – the width/height of another element – you should use vh and vw.
Your code would be:

your table {
  width: 100vw;
  height: 100vh;
}

But, if the document is smaller than 100vh or 100vw, then you need to set the size to the document's size.

(table).style.width = window.innerWidth;
(table).style.height = window.innerHeight;
