How to make a scrollable table with fixed header - javascript

I am trying to make a scrollable table with vertical and horizontal scroll bars and with fixed header.
But when i try to make the header in fixed position,my vertical scroll bar becomes hidden and appears only when i scroll extreme right.
similarly,if i make the scroll bars visible,my header becomes movable.
Please advise.
PFB my CSS code.
.button-container{
text-align: center;
}
table {
border-collapse: collapse; /* make simple 1px lines borders if border defined */
}
tr {
width: 100%;`}
.outer-container {
position: absolute;
top:0;
left: 0;
right: 300px;
bottom:40px;
overflow: hidden;
}
.inner-container {
width: 100%;
height: 100%;
position: relative;
overflow-y:hidden;
}
.header-table-container {
float:left;
width: 100%;
}
.header-table{
background: #0088CC;
width=100%;
cellpadding=0;
cellspacing=0;
}
.body-table-container {
float:left;
height: 100%;
}
.body-table{
width=100%;
cellpadding=0;
cellspacing=0;
height:500px;
}
.header-cell {
background-color: yellow;
text-align: left;
height: 40px;
}
.body-cell {
background-color: blue;
text-align: left;
}
.headerCol {
width: 160px;
min-width: 160px;
text-align: center;
}
.bodyCol {
width: 160px;
min-width: 160px;
}
.resultsCol {
width: 250px;
min-width: 250px;
}
.even {
background: lightgrey;
}
.button-container{
text-align: center;
}
.results{
text-align: left;
}
#preprod-wrapper{
}
#prod-wrapper{
height:500px;
}


Its not too easy, but take a look here:
https://fiddle.jshell.net/805s75hb/
Many things were used here, such as position and overflow.
I hope it can help you. :)


Have you tried this?
table {
border-collapse: collapse;
overflow :scroll;
}


I have used two tables one for header to make it static so that it would fixed.
Have a look if this can help you :)
.wrap {
width: 352px;
}
.wrap table {
width: 300px;
table-layout: fixed;
}
table tr td {
padding: 5px;
border: 1px solid #eee;
width: 100px;
word-wrap: break-word;
}
table.head tr td {
background: #eee;
}
.inner_table {
height: 100px;
overflow-y: auto;

I reviewed your codepan and conclude with that, You need to add some CSS property in your CSS file and it's work.
tbody {
height: 200px;
display: inline-block;
overflow: auto;
}
thead tr th{
position: sticky;
top:0;
left:0;
right:0;
}

set position sticky of header
and for table overflow-y set as auto
.fixTable {
overflow-y: auto;
height: 110px;
}
.fixTable thead th {
position: sticky;
top: 0;
}
table {
border-collapse: collapse;
width: 100%;
}
th,
td {
padding: 8px 15px;
border: 2px solid #529432;

How to display a circle within a td by adding a class?

I have a table and I would like to change a class on the td by clicking them. When I addClass() each cell changes but it seems override any class.
My desired result for each cell is like this:
How can I achieve this by adding a class to them?
$(function() {
$("td").click(function() {
$(this).addClass('outpatient');
});
});
table td {
width: 20px;
overflow: hidden;
display: inline-block;
white-space: nowrap;
border: 1px solid gray;
text-align: center;
padding: 5px;
cursor: pointer;
background-color: aqua;
}
.outpatient {
background-color: yellow;
border-radius: 50%;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
<tr>
<td>4</td>
<td>5</td>
<td>6</td>
</tr>
<tr>
<td>7</td>
<td>8</td>
<td>9</td>
</tr>
</table>

To achieve this can create another element inside each td. The td will be used to display the square with the teal background. The inner element is necessary to show the circle with the yellow background. By default the circle can be hidden, and then displayed when the class is added to the parent td. Try this:
$(function() {
$("td").click(function() {
$(this).addClass('outpatient');
});
});
table td {
overflow: hidden;
white-space: nowrap;
border: 1px solid gray;
text-align: center;
cursor: pointer;
background-color: aqua;
padding: 0;
margin: 0;
position: relative;
}
td div {
width: 32px;
height: 32px;
border: 1px solid transparent;
line-height: 32px;
margin: -1px;
box-sizing: border-box;
}
td.outpatient div {
background-color: yellow;
border-radius: 50%;
border-color: gray;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table>
<tr>
<td><div>1</div></td>
<td><div>2</div></td>
<td><div>3</div></td>
</tr>
<tr>
<td><div>4</div></td>
<td><div>5</div></td>
<td><div>6</div></td>
</tr>
<tr>
<td><div>7</div></td>
<td><div>8</div></td>
<td><div>9</div></td>
</tr>
</table>

You can consider background-image with radial-gradient to create the circle above the background-color
$(function() {
$("td").click(function() {
$(this).addClass('outpatient');
});
});
table td {
width: 20px;
overflow: hidden;
display: inline-block;
white-space: nowrap;
border: 1px solid gray;
text-align: center;
padding: 15px;
cursor: pointer;
background-color:aqua;
}
.outpatient {
background-image:
radial-gradient(farthest-side,yellow calc(100% - 3px),#000 calc(100% - 2px),transparent 100%);
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

.slideToggle() hides element when it reaches the top of the page, animation appears cut short

I'm creating a mobile navigation that slides down, and I'm using .slideToggle() to animate it
fiddle
html
<table id=menu>
<tr>
<td align="center">link</td>
<td align="center">link</td>
</tr>
<tr>
<td align="center">link</td>
<td align="center">link</td>

<td align="center">link</td>
<td align="center">link</td>

css
#menu {
display: none;
position: absolute;
margin-top: 50px;
width: 100%;
height: 150px;
background-color: #fff;
z-index: 8;
}
tr {
height: 50px;
}
js
$(".toggle").click(function() {
$("#drop").toggleClass('flip');
$("#menu").slideToggle(300);
});
but the table is taller than my header and when the it slides to the top of the page it just disappears instead of finishing the slide animation (see fiddle).
Any way to solve this? Or a better animation to use?
Thanks!

What you're seeing is the margin-top animating - but jQuery cannot animate the height of a <table> element (more info in similar thread). Wrap the <table> in a <div> element and animate that, like so:
$(document).ready(function() {
$(".toggle").click(function() {
$("#drop").toggleClass('flip');
$("#menu").slideToggle(300);
});
});

i think this issue with your table, i have put a div before the table, now the issue is solved
$(function(){
$(".toggle").click(function() {
//$("#drop").toggleClass('flip');
$("#menu").slideToggle(400);
});
});

Tooltip window changing height and width when more text is added

i tried to make this tooltip dynamic with the text (so when there is less text - smaller window) but it didn't work for me. I need this tooltip to change size of itself when more text is added and shrink itself when there is only a few words. Example in Jsfiddle.
PS: I don't like to use JS, but if it's necessary I can live with that.

Removing the width property from the tooltip css should work. Remove the height too if you want it to adapt when resizing the window.

Are you trying to achieved something like this
.content {
position: static;
}
.header {
text-align: center;
position: relative;
margin-top: 40px;
}
th, td{
border:1px solid black;

}

background-color: #eff0f0;

background-color: #eed6b1;

In your code you have a fix value for your tooltip width and height.
If you need to make the toolip width and height adjusted dynamically by its content you should remove the width and height value.
Edit based on your comment.
If you need to keep some space between the tooltip and your view port you can use margin property, this will allow some space on each d side of your tooltip.
Try to comment out as in the follow example:
https://jsfiddle.net/d4m5hj6f/6/
.tooltip {
position:absolute;
display: none;
background-color: #fafbb8;
border: 1px solid black;
border-radius: 4px;
margin: 28px;
padding: 10px;
position:absolute;
z-index: 1000;
/*width: 680px;*/
/*height: 50px;*/
font-weight: bold;
}

Table expands on "tr:before"

I'm trying to achieve a sort of selection effect on a table that I'm currently working on. I want to do this by adding a class to the table row that the user clicks. The class that gets added to the row will add a small circle to the left of the row. However, as I'm adding the class to the row, the table (or the row) seems to expand a few pixels. I can't figure out why.
Some example code to illustrate my problem:
document.querySelector('tr').addEventListener('click', function() {
if (!this.classList.contains('clicked')) {
this.classList.add('clicked');
return;
}
this.classList.remove('clicked');
});
table {
position: relative;
background: #ccc;
margin: 5rem auto;
}
.clicked:before {
position: absolute;
content: '';
right: 100%;

Any help would be much appreciated!

You could add your clicked:before element and set it's opacity to 0 and then on the click event add another class to actually show the element.
document.querySelector('tr').addEventListener('click', function() {
if (!this.classList.contains('show-clicked')) {
this.classList.add('show-clicked');
return;
}
this.classList.remove('show-clicked');
});
table {
position: relative;
background: #ccc;
margin: 5rem auto;
}
tr {
margin-left: 10px;
}
.clicked:before {
position: absolute;
content: '';
right: 100%;
top: 50%;
width: 10px;
height: 10px;
border-radius: 50%;
background: yellow;
opacity: 0;
}
.show-clicked:before {
opacity: 1;
}
<table>
<tr class="clicked">
<td>1</td>
<td>Two</td>
<td>3</td>
<td>Four</td>
<td>1</td>
<td>Longer text..</td>
<td>3</td>
<td>Four</td>
</tr>
</table>

I have a trick. I hope it works as what you want
document.querySelector('tr').addEventListener('click', function() {
if (!this.classList.contains('clicked')) {
this.classList.add('clicked');
return;
}
this.classList.remove('clicked');
});
table {
position: relative;
background: #ccc;
margin: 5rem auto;
}
.show-me {
width: 10px;
height: 10px;
border: 0;
background-color: transparent;
}
.show-me span {
display: none;
width: 10px;
height: 10px;
border-radius: 50%;
background: yellow;
}
.clicked .show-me span {
display: block;
}
<table>
<tr>
<td class="show-me">
<span></span>
</td>
<td>1</td>
<td>Two</td>
<td>3</td>
<td>Four</td>
<td>1</td>
<td>Longer text..</td>
<td>3</td>
<td>Four</td>
</tr>
</table>

You could use the css visibility property and an extra class. This way any effect that is caused by ::before will be in the rendering but just not visible.
Summary The visibility property can be used to hide an element while
leaving the space where it would have been. It can also hide rows or
columns of a table.
document.querySelector('tr').addEventListener('click', function () {
this.classList.toggle('visible');
});
table {
position: relative;
background: #ccc;
margin: 5rem auto;
}
.clicked::before {
position: absolute;
content:'';
right: 100%;
top: 50%;
width: 10px;
height: 10px;
border-radius: 50%;
background: yellow;
visibility: hidden;
}
.visible::before {
visibility: visible;
}
<table>
<tr class="clicked">
<td>1</td>
<td>Two</td>
<td>3</td>
<td>Four</td>
<td>1</td>
<td>Longer text..</td>
<td>3</td>
<td>Four</td>
</tr>
</table>

This post helped me solve the problem. Seems :before actually "creates" a new table cell. Had to add the :before to the first <td> in my code instead of the <tr>.
Is it possible to use pseudo-elements (:after, :before) inside a table row?
