Puppeteer - thead overlapping on page break ONLY when thead is cut off by footer on previous page

What I am trying to do?
I am using Puppeteer to convert raw HTML to PDF. I have saved the HTML code in a file, and I'm reading from that file and converting it to PDF.
What is the problem
The thead is NOT overlapping on every page, NO.
It is ONLY overlapping when a thread has multiple rows and half of it gets cut off because of the page break. On the next page, the remainder of the thead is printed ALONG with the overlapped entire thead.
Here is the Output of the converted PDF Overlapping thead
<table id='TblCustomerRating' class='display unbreakable' border='1' cellspacing='0' cellpadding='0'
style=' width: 100%;border-collapse:collapse;'>
<thead>
<tr>
<th class='Greyheader' align="center" style="padding-top: 5px; padding-bottom: 5px;" colspan="4">Askari
Cement Limited</th>
</tr>
<tr>
<th class='Greyheader' align="center" style="padding-top: 5px; padding-bottom: 5px;" colspan="4">External

</tr>
<tr class='Greyheader'>
<th width="12%" align="center" class='Greyheader'><b> ECAI</b> </th>
<th width="12%" align="center" class='Greyheader'><b>Long Term</b></th>
<th width="12%" align="center" class='Greyheader'><b>Short Term</b></th>
<th style='display:none' width="12%" align="center" class='Greyheader'><b>Rating Date</b></th>
</tr>
</thead>
<tbody>
<tr id="4" type="data" LT="" ST="" MT="" class=" GreyBorder">
<td width="10%" agencyCode='4' class='GreyBorder'
style='background-color:lightgray;text-align: center;padding-top: 5px;padding-bottom: 5px;font-weight: bold;width:10%;'>
JCR-VIS</td>
<td width="10%" RsCode='35' class='GreyBorder' align="center">A</td>
<td width="10%" RsCode='' class='GreyBorder' align="center"></td>
<td align="center" style='display:none' class='GreyBorder'></td>
</tr>
</tbody>
</table><br />
What I have tried?
I have tried adding the following CSS: (it didn't work)
table { overflow: visible !important; }
thead { display: table-header-group !important; }
tr { page-break-inside: avoid !important; }
NOTE:
I repeat, the overlapping is not occurring when the table rows are cut off from page-break. It is ONLY overlapping when thead is cut off because of the page break. as shown in the image above.
Puppeteer version
1.19.0
Node.js version
v16.13.0
npm version
8.1.0
What operating system are you seeing the problem on?
Windows

I think I had the same issue. It is when you have a repeating table header (thead { display: table-header-group }) and the table breaks for printing between tr tags within thead. I couldn't find a way to do it with only the break-after, break-before or break-inside properties. This is a bit of a hack, but here is how I fixed it:
:root {
--header-height: 60px;
}
th {
break-inside: avoid;
}
thead th::after {
content: '';
display: block;
height: var(--header-height);
margin-bottom: -var(--header-height);
break-inside: avoid;
}
The height and negative margin-bottom are equal to the height of the tr elements below the first tr. In my code I just have 60px and -60px hard coded in, but I wanted to be clear that depending on the height of your table header that you will have to change those values. The height creates the size of element that can't be broken inside by a page break and the negative margin-bottom brings back up the table content so that it is not impacted by the existence of the pseudo-element. It essentially forces the header to be on the next page.

face the same problem.
You may put the content of <td> into <div> tag.

bootstrap table not responsive even with .table-responsive .table

this is the code of my bootstrap table everything is okay but when i switch to mobile it is not adding that horizontal scroll i have already added table-responsive class outside element with class .table but still it ain't working for mobile devices
<div class="table-responsive table-area">
<table class="table table-striped table-dark bordered-table">
<thead>
<tr>
<th scope="col">✔️</th>
<th scope="col">Questions</th>
<th scope="col">❤️</th>
</tr>
</thead>
<tbody>
<% allLists.forEach(item=>{ %>
<tr>
<th scope="row"> <input class="form-check-input checkbox-solved" type="checkbox" value="" id="flexCheckDefault"> </th>
<td> <%= item.name %> </td>
<td> <input class="form-check-input checkbox-favourite" type="checkbox" value="" id="flexCheckDefault"> </td>
</tr>
<% }) %>
</tbody>
</table>
</div>
in the mobile view it is no even displaying that green tick table coulmn
this is table css code
.table-area {
margin-top: 50px;
max-width: 1000px;
}
.table-area table {
text-align: center;
}
table a{
font-family: 'Roboto', sans-serif;
text-decoration: none;
font-size: 1.1rem;
color: #fff;
}
table a:hover {
color: goldenrod;
}
i thought max-width was causing issues but i tried removing it too but it is still not working.
Can someone please help me with this code?

As you can see from image your fourth question text is without any space and hence it's not wrapping. Typically when you expect such a long strings without the whitespace, we need to set the width so that it will force to wrap. In your case you might have to Responsive Web Design - Media Queries
Here is sample for wrap with fixed width. However you can combine media queries to achieve desired result on various devices
<!DOCTYPE html>
<html>
<head>
<title>Title of the document</title>
<style>
span {
width: 135px;
word-wrap: break-word;
display: inline-block;
}
</style>
</head>
<body>
<span>

Contextual menu on mouseover

I'm facing a little problem with my code :
<style>
.btn_remove{
position:absolute;
right:-25px;
}
.test:hover > table{
background-color:#708ab3;
}
</style>
<a href="page/ABC" class="test" ng-mouseenter="showRemove = true" ng-mouseleave="showRemove = false">
<div class="btn_remove" ng-show="showRemove"><img src="../../gfx/btn_remove.png" height="28" width="26" border="0"/></div>
<table cellpadding="0" cellspacing="0" border="0" width="100%">
<tr>
<td>mercedes class a</td>
<td>70'000</td>
</tr>
<tr>
<td><i>Nice car</i></td>
<td>Color: Red</td>
</tr>
</table>
</a>
So as you can see I have a table into a <a href>. When I pass my mouse over the table it calls the class .test:hover > table and also set the angular variable showRemove = true which will then show the absolute div on the right of the table.
My problem is when I mouse over the absolute div, it has the href from the parent (page/ABC).
If I try to write
<div class="btn_remove" ng-show="showRemove"><img src="../../gfx/btn_remove.png" height="28" width="26" border="0"/></div>
then nothing is working because the first link isn't closed.
How could i manage to get :
Mouseover on table = background change + link (page/ABC) + show remove image on the right.
Mouseover on remove image = JS function to be called or whatever but do not be part of the parent link.
Mouseout of table or remove image = remove "remove image" and remove background change.
All this without using jquery. JS or angular, but i guess it's mostly div and css.
Solution:
<style>
.test{
position:absolute;
right:-25px;
visibility:hidden;
}
.wrapper:hover table{
background-color:#708ab3;
}
.wrapper:hover .test
{
visibility:visible;
}
</style>
<div class="wrapper">
<div class="test"><img src="../../gfx/btn_remove.png" height="28" width="26" border="0"/></div>
<a href="table link">
<table cellpadding="0" cellspacing="0" border="0" width="100%">
<tr>
<td>Mercedes Class A</td>
<td>70'000</td>
</tr>
<tr>
<td><i>Nice car</i></td>
<td>Red</td>
</tr>
</table>
</a>
</div>

Glad to hear you got it working.
for reference you can add javascript:; to the href of an anchor to make it not do anything.
You can select a child element on hover using:
.parent:hover .child
{
the hover styles for the child
}
here is the fiddle for anyone else who needs to select a child element on hover jsfiddle.net/jE7J6

How to change table background onmouseover?

I have tabs one says 'Search' and the other says 'Tags'
Search is the default tab so it has a grey rounded edge table background while 'Tags' has a white rounded edge background.
I want to be able to put the mouse over 'Tags' and the background to change from white to grey. How is this done?
Here is the HTML code:
<div class="roundedcornr_box_407494">
<div class="roundedcornr_top_407494"><div></div></div>
<div class="roundedcornr_content_407494">
<font color="#ffffff" size="2" face="helvetica">
Search
</font>
</div>
<div class="roundedcornr_bottom_407494"><div></div></div>
</div>
</td>
</tr>
</table>
</td>
<td>
<div style="margin-left:10px;" />
<center>
<table height="20" width="30" cellpadding="0" cellspacing="0">
<tr>
<td>
<center>
<div class="roundedcornr_box_235759">
<div class="roundedcornr_top_235759"><div></div></div>
<div class="roundedcornr_content_235759">
<font color="#585858" size="2" face="helvetica">
Tags
</font> </div>
<div class="roundedcornr_bottom_235759"><div></div></div>
</div>
</center>
</td>
</tr>
</table>
And CSS:
.roundedcornr_box_407494 {
background: #bdbdbd;
}
.roundedcornr_top_407494 div {
background: url(roundedcornr_407494_tl.png) no-repeat top left;
}
.roundedcornr_top_407494 {
background: url(roundedcornr_407494_tr.png) no-repeat top right;
}
.roundedcornr_bottom_407494 div {
background: url(roundedcornr_407494_bl.png) no-repeat bottom left;
}
.roundedcornr_bottom_407494 {
background: url(roundedcornr_407494_br.png) no-repeat bottom right;
}
.roundedcornr_top_407494 div, .roundedcornr_top_407494,
.roundedcornr_bottom_407494 div, .roundedcornr_bottom_407494 {
width: 100%;
height: 5px;
font-size: 1px;
}
.roundedcornr_content_407494 { margin: 0 5px; }
Thanks!

With :hover.
Sample:
http://jsfiddle.net/stKn3/

With Css
table:hover
{
background-color:gray;
}
or
table tr:hover
{
background-color:gray;
}

I think its better to have a single images as background(with corners #as you trying to do) of the tabs And changing the background image on mouseover event. Instead of splitting them and merging the pieces together again by div tags.
Follow these examples :
http://www.codefoot.com/javascript/script_image_textarea_mouseover.html
http://www.codebelly.com/javascript/backimagechange.html

Try this
<TR onMouseover="this.bgColor='#EEEEEE'"onMouseout="this.bgColor='#FFFFFF'">
<td>Some data</td>
</TR>
OR
<table onMouseover="this.bgColor='#EEEEEE'" onMouseout="this.bgColor='#FFFFFF'">
</table>
EDIT:
Try this complete HTML.
<html>
<body>
<table >
<tr onMouseover="this.bgColor='#EEEE00'" onMouseout="this.bgColor='#FFFFFF'">
<td>
Some Data on table's first row
</td>
</tr>
</table>
</body>
</html>
It needs some modifications to use on your code. Try it on your own.

dynamically change css class using js

I'm having a problem while trying to dynamically change a table cell's styling class using JavaScript.
The following issue happens on FF, I opened the page on other browsers too and it worked fine.
I have a html page that contains a 4x4 table. I would like when I click on a cell, to zoom it in and when I click on it again to zoom it out. I defined 2 CSS classes, one for the normal size cell and one for the zoomed cell. I am using JS to change the CSS class when a cell is clicked.
The issue on FF is that when changing from zoomClass to normalClass all the cells to the right of the clicked cell are shifted to the right...
I can't find a solution or a workaround for this problem, if somebody has any ideas please post them here.
Next, I will attach the html, css and js files.
Thanks :)
util.js
function zoom(id) {
if (document.getElementById(id).className == "zoomClass") {
document.getElementById(id).className = "normalClass";
} else {
document.getElementById(id).className="zoomClass";
}
}
calendar.css
table, td, th, tr {
border-color:#D2D3D4;
border-style:solid;
border-width:2px;
}
#main_table {
border-spacing:1px;
height:450px;
margin-left:auto;
margin-right:auto;
position:relative;
top:30px;
width:850px;
}
td.normalClass {
padding:0;
font-size:4px;
color:#3333FF;
}
td.zoomClass {
display:inline;
position:absolute;
width:320px;
height:240px;
z-index:100;
font-size:18px;
}

Unfortunately "position" doesn't work on table cells. You could try putting a div inside the table cell and positioning that.
Edit: Something like this should do the trick:
td.normalClass div {
display: none;
}
td.zoomClass div {
display: block;
position: absolute;
width: 320px;
height: 240px;
}
Make sure the div is the first thing in the td and it'll be positioned at the td's top left corner. You might need to play with relative positioning on the td if you need to change the top and left values further.

This is how tables work. I possible I would try and do the same thing using divs and then you should be able to deal with the problem using position:absolute so the expanded div will overlay the others. This could work the same for a table cell.

A few comments on your code, if I may. I would keep the layout in the CSS file and not in the HTML, so I'd remove all of those align="right" and valign="top". Also, you can reference the cells in your table much more efficiently. Then you won't have to set the class for each cell.
#main_table td{
padding:0;
font-size:4px;
color:#3333FF;
}
I would also keep all of the behaviour of the page in a separate script file (Javascript). So no more onclick="zoom(x)" at every cell. You can use event binding to do that.
Also, if you use event binding, you can just "read" the id of the clicked cell, so you don't have to pass that value in statically in the call of the zoom function.
Lastly: I can highly recommend using jQuery to do this kind of DOM manipulation as it's a lot easier, the code is shorter and more readable and your scripts work across browsers pretty much out of the box.
I don't have a solution for this specific problem but using jQuery it's quite easy to insert a new DOM element, a div for instance, with the content of the clicked cell, float over the table and simulate the zoom effect. That div would be be absolutely positionable and can be styled a lot better than the cell the user clicked on.
