I have a solution by which I can create scrollable tables w/fixed header/footer using minor jQuery and CSS - but I am looking for a way to make this a CSS-only solution that is cross-browser compliant.
To be clear, what I am seeking to do is use only a table
tag (and it's valid sub-tags, colgroup
, col
, thead
, tbody
, tfoot
, tr
, th
, td
), but adopt a set of CSS rules which will meet the following conditions:
This code example: http://jsfiddle.net/TroyAlford/SNKfd/ shows my current approach. Most of the JS is just to populate the table with random values, but the last portion is what drives the left/right scrollability.
$tbody.bind('scroll', function(ev) {
var $css = { 'left': -ev.target.scrollLeft };
$thead.css($css);
$tfoot.css($css);
});
NOTE: The example provided does not render properly in IE, and requires jQuery to provide the horizontal scrolling. I don't care about horizontal scrolling anyway, so it's fine if a solution doesn't do that.
Check support of position: sticky
before using this solution: https://caniuse.com/#feat=css-sticky
position: sticky
An alternative answer would be using position: sticky
. As described by W3C:
A stickily positioned box is positioned similarly to a relatively positioned box, but the offset is computed with reference to the nearest ancestor with a scrolling box, or the viewport if no ancestor has a scrolling box.
This described exactly the behavior of a relative static header. It would be easy to assign this to the <thead>
or the first <tr>
HTML-tag, as this should be supported according to W3C. However, both Chrome, IE and Edge have problems assigning a sticky position property to these tags. There also seems to be no priority in solving this at the moment.
What does seem to work for a table element is assigning the sticky property to a table-cell. In this case the <th>
cells.
Because a table is not a block-element that respects the static size you assign to it, it is best to use a wrapper element to define the scroll-overflow.
div {
display: inline-block;
height: 150px;
overflow: auto
}
table th {
position: -webkit-sticky;
position: sticky;
top: 0;
}
/* == Just general styling, not relevant :) == */
table {
border-collapse: collapse;
}
th {
background-color: #1976D2;
color: #fff;
}
th,
td {
padding: 1em .5em;
}
table tr {
color: #212121;
}
table tr:nth-child(odd) {
background-color: #BBDEFB;
}
<div>
<table border="0">
<thead>
<tr>
<th>head1</th>
<th>head2</th>
<th>head3</th>
<th>head4</th>
</tr>
</thead>
<tr>
<td>row 1, cell 1</td>
<td>row 1, cell 2</td>
<td>row 1, cell 2</td>
<td>row 1, cell 2</td>
</tr>
<tr>
<td>row 2, cell 1</td>
<td>row 2, cell 2</td>
<td>row 1, cell 2</td>
<td>row 1, cell 2</td>
</tr>
<tr>
<td>row 2, cell 1</td>
<td>row 2, cell 2</td>
<td>row 1, cell 2</td>
<td>row 1, cell 2</td>
</tr>
<tr>
<td>row 2, cell 1</td>
<td>row 2, cell 2</td>
<td>row 1, cell 2</td>
<td>row 1, cell 2</td>
</tr>
<tr>
<td>row 2, cell 1</td>
<td>row 2, cell 2</td>
<td>row 1, cell 2</td>
<td>row 1, cell 2</td>
</tr>
</table>
</div>
In this example I use a simple <div>
wrapper to define the scroll-overflow done with a static height of 150px
. This can of course be any size. Now that the scrolling box has been defined, the sticky <th>
elements will corespondent "to the nearest ancestor with a scrolling box", which is the div-wrapper.
