Keep table header visible without showing scrollbars in table body
I am making a page with tabular data is scrollable with main page scrollbar but with keeping table header visible. There's a page header that sticks on top and pagination area that sticks on bottom on the page.
I gave it a try here.
var dataHeader = document.querySelector('.data thead');
var scrollValue = 50;
window.onscroll = function () {
if (document.body.scrollTop > scrollValue || document.documentElement.scrollTop > scrollValue) {
dataHeader.className = "fixed";
} else {
dataHeader.className = "";
}
};.main {
position: relative;
top: 0;
width: 700px;
margin: 0 auto;
}
.header {
position: fixed;
top: 0;
background-color: #abc;
width: 700px;
z-index: 10;
}
.content {
position: relative;
top: 60px;
background: #cfe;
}
.content-header {
color: blue;
padding-top: 10px;
}
.data {
position: relative;
margin-bottom: 18px;
}
.data table {
border-collapse: collapse;
width: 700px;
}
.data thead {
background: grey;
width: 700px;
display: table-header-group;
}
.data tbody {
width: 700px;
}
.data thead.fixed {
position: fixed;
top: 80px;
}
.data thead.fixed th {
width: 90px;
}
.paging {
position: absolute;
bottom: 0;
background-color: black;
color: white;
width: 700px;
}
.column {
padding: 2;
width: 80px;
}<div class="main">
<div class="header">
<h1>Super Page</h1>

<div class="content-header">

You can adjust your .data thead.fixed th rule to width: calc(700px/3); like so:
var dataHeader = document.querySelector('.data thead');
var scrollValue = 50;
window.onscroll = function () {
if (document.body.scrollTop > scrollValue || document.documentElement.scrollTop > scrollValue) {
dataHeader.className = "fixed";
} else {
dataHeader.className = "";
}
};.main {
position: relative;
top: 0;
width: 700px;
margin: 0 auto;
}
.header {
position: fixed;
top: 0;
background-color: #abc;
width: 700px;
z-index: 10;
}
.content {
position: relative;
top: 60px;
background: #cfe;
}
.content-header {
color: blue;
padding-top: 10px;
}
.data {
position: relative;
margin-bottom: 18px;
}
.data table {
border-collapse: collapse;
width: 700px;
}
.data thead {
background: grey;
width: 700px;
display: table-header-group;
}
.data tbody {
width: 700px;
}
.data thead.fixed {
position: fixed;
top: 80px;
}
.data thead.fixed th {
width: calc(700px/3);
}
.paging {
position: absolute;
bottom: 0;
background-color: black;
color: white;
width: 700px;
}
.column {
padding: 2;
