Scrollable table with fixed columns and header, with modern CSS
How to make a table with so little JavaScript as possible using modern CSS?
The features I'm trying to have is:
Note: I did see and analyse some of the most popular/seen questions and answers in SO, like here and here for example.
I know this can be done with JavaScript event handlers for scroll so that a fixed column can be moved down/up to follow the main column. A example of the functionality I am trying to build (but heavily scripted) could be like this. We can also add MutationObserver in the parent element to the table to detect size changes and calculate again the sizes of the table. But this is expensive in performance, and since CSS is also evolving and modernizing I wonder if there are new ways...
Is there a 2017/2018 solution for this that is only CSS or as little JS overhead as possible?
I would like to avoid having to implement JavaScript solutions that break so easy like this:
My ideas:
a) : use position: fixed; in the fixed columns
Problems:
<td> elements height has to be defined or calculated by JavaScript. b) : use div(s) to "fake" the left column and have the scrollable content in the table
Problems:
c) : use N tables show only parts of each so I can have HTML markup but keep fixed header/columns.
Problems:
Using a scroll event listener and a fixed left column we can use JavaScript like this:
const firstColumn = [...document.querySelectorAll('table tr > *:first-of-type')];
const tableContainer = document.querySelector('.table-container');
tableContainer.addEventListener('scroll', function() {
const currentScrollPosition = this.scrollTop * -1;
firstColumn.forEach(el => el.style.marginTop = currentScrollPosition + 'px');
});.table-container {
width: 600px;
height: 300px;
overflow-x: scroll;
overflow-y: scroll;
}
.table-scroller {
width: 1000px;
}
table {
width: 100%;
margin-left: -13px;
table-layout: fixed;
border-collapse: collapse;
border: none;
}
table th,
table td {
padding: 0.8em;
border: 1px solid;
background-color: #eeeeef;
}
table th {
background-color: #6699FF;
font-weight: bold;
}
table tr {
height: 60px;
vertical-align: middle;
}
table tr > *:first-of-type {
position: fixed;
width: 50px;
margin-left: 13px;
margin-top: 0;
height: inherit;
}<div class="table-container">
<div class="table-scroller">

</div> Maybe you could try to use the recent position:sticky to achieve it. Or, at least, to start the aproach with less javascript.
