why jupyter notebook cannot display html 'table', but other html elements are okay, and how can I solve this problem?
below is my source code and my result
source code
<table style="width:20%">
<tr>
<td> **L1** </td>
<td> 1.1 </td>
</tr>
</table>
result
<tr>
<td> **L1** </td>
<td> 1.1 </td>
</tr>
it only removes tag <table> and does nothing else.
That's interesting, because the table (created by pasting your code) comes out just fine for me:
From my personal experience, I can definitely say that Markdown in jupyter notebooks is somehow volatile/unpredictable when it comes to HTML. For example, I myself have been looking for a fix for Jupyter just arbitrarily doing line breaks in the table header (esp. in formulas) and I have found this fix, but it doesn't work for me at all.
I know this is not particularly helpful, but at least it demonstrates that the table not being rendered correctly in your case was either some unexpected behaviour or some bug which maybe, or maybe not, has been fixed in the course of the last year.
You can also add the magic command before the table tag, which worked for me.

I have a very complex dynamic table that I need to output to pdf in laravel 5.6. The project I inherited had Dompdf installed and is already rendering all other content. Therefore, I use it as well for compatibility.
My issue is I have a table to render consisting of 13 columns and undefined number of rows, where intermittently a column may span 13 columns for a heading or a row may span several rows at any given time or a colspan within the rowspan that spans 11 columns from the 3rd row. No html is hardcoded except the <table>, <thead>, <th> and <tbody> tags. The html within the tbody tag is dynamically generated depending on the array data.
Everything looks great in the browser and when I view() the pdf blade as well as ctrl + p it creates a nice pdf, although for some reason rowspan cells spanning to the next page does not carry over markup and content. As soon as I try to stream() the pdf the table becomes warped and looks like a toppled building built by Picasso.
Here is links to pdf's, the one I ctrl + p lost its colour due to me removing names.

Can someone please help and give me a clue on how to output such a complex table with Dompdf? As I would really want to keep on using only one PDF rendering library in this project.
Otherwise I am open to suggestions to use another pdf library that can handle rowspan that span pages and this complex layout?
Update
Based on a comment by Don't panic (he suggested validating html and fill empty td tags with ), that he subsequently deleted.
I re-wrote the HTML as a template into my pdf.blade.php view. Now, I only output the values in a loop in my view. Firstly, it becomes easier to maintain and to leave off the validation he suggested. I also filled every empty <td> tag with a hardcoded ' '. This is to more easily see why certain rows end where they should and others not. The result is sadly still the same, a warped table. But it does seem to be a rowspan issue not colspan. The 'rowspan' rows stack after another. So maybe missing a td tr.
Solved rowspan stacking issue
Two weeks of testing and only problem was it was not outputting certain rows' opening tags, which lead to rows not knowing when to begin. Now only problem left is rowspan across pages.
Update on update
So I have really tried everything I can to get DomPdf to do what it is suppose to do, which is rendering pdf's. I have read a bit more and found that this library has a long standing issue of not being able to render rowspan accross pages. Therefore, on to the next rendering library wkhtlmpdf or I could logically divide rowspans to stop at end of page and start again on new page. Will have to check my watch on this one.
As described in this and this answers, we can use HTML tags in Markdown to create tables with cells spanning multiple rows or columns. Suppose I want to make the following table (rendered by Visual Studio Code with extension "Markdown All in One"):
Desired Effect
But the problem for the second answer is that the rowspan/colspan of the first column/row will be rendered with a additional column/row in the front, as in the following example (does not work on StackOverflow, but works in VSCode; a work-around is to add an empty column/row, as suggested by the first comment in that answer, but this is still not perfect):
||Letter|Typesetting|Result|
|-|-|-|-|
|<td rowspan=4>a |Normal|a
||Italic|*a*|
||Bold|**a**|
||Math|$a$
Result:
Table constructed using method in Answer 2
Then we can use the HTML tags, as described by the first answer:
<table>
<thead>
<tr> <th>Letter <th>Typesetting <th>Result
</thead>
<tbody>
<tr> <td rowspan=4>a <td>Normal <td>a
<tr> <td>Italic <td>*a*
<tr> <td>Bold <td>**a**
<tr> <td>Math <td>$a$
</tbody>
</table>
But then Markdown formatting will be lost:

Is there any way to overcome this problem, i.e. using HTML tags to achieve rowspan/colspan without loss of Markdown text formatting?
I've actually created a template on Mailchimp. I used a basic template of Mailchimp and transformed it into the design they gave me. I used the the CSS inline tool of Mailchimp to insert all the code in an inline mode as Gmail does not accept any style on the header. I only have this issue on Gmail, the rest work perfectly. What can I do?
As the code is long I inserted it in a fiddle if you wish to check it out:
http://jsfiddle.net/z27Bw/
I need an answer as its a mystery for me!
You have 2 unclosed <td> tags in the HTML -- one on line 476, one on 482. That might be what's causing the issue in Gmail. If that doesn't fix it, I'd say yeah, it might be a colspan issue.
you can try this
Write first tr code like this
<tr>
<td colspan="2" height="281"> </td>
</tr>
instead of
<tr>
<td width="35" height="281"> </td>
<td class="headerContent"> </td>
</tr
>
and then put that big header image inside it.
I'm going though something quite weird. I was working on a chat system with the rows and stuff based on tables, but the formatting kept messing up. I wondered why until I looked at the part of the source which was not working, which looked like this:
<table border="0">
<tbody>
<tr class="chatline" style="background:white;border-style:none;border-top:1px solid grey;padding:0px;">
<td style="background:#A0D7FF;margin:0px;width:1%;"><span style="padding:2px;background:#A0D7FF;color:black;height:100%;border-right:1px solid grey;">kpsuperplane</span></td>
<td style="color:black;background:white;"><span style="color:black;padding:2px;">test</span></td>
</tr>
<tr class="chatline" style="background:white;border-style:none;border-top:1px solid grey;padding:0px;">
<td style="background:#A0D7FF;margin:0px;width:1%;"><span style="padding:2px;background:#A0D7FF;color:black;height:100%;border-right:1px solid grey;">kpsuperplane</span></td>
<td style="color:black;background:white;"><span style="color:black;padding:2px;">test</span></td>
</tr>
</tbody>
</table>
However, when I view it through dev tools in chrome, I get this:
<table border="0">
<tbody>
<span style="padding:2px;background:#A0D7FF;color:black;height:100%;border-right:1px solid grey;">kpsuperplane</span>
<span style="color:black;padding:2px;">test</span>
<span style="padding:2px;background:#A0D7FF;color:black;height:100%;border-right:1px solid grey;">kpsuperplane</span>
<span style="color:black;padding:2px;">test</span>
</tbody>
</table>
Any idea why this is happening? The td's and tr's are automatically removed from the document when they are rendered. And this is not chrome specific. Live code in dreamweaver gives the same puzzling result.
Pic below:
I tested this in jsfiddle and it doesn't seem to be a problem. I also tested it in my own environment (chrome) and it works fine. Try looking for an unclosed tag in code above the table.
Edit:
Paste the code into w3c validator http://validator.w3.org/check. I found 13 errors/warning in the html. Check out the errors and the specific line numbers.
I found that you have div tags within the table, but they are not wrapped by a tr. I'm sure you'll be able to find the rest within the validators output.
According to your jsfiddle: you have simple mistake in HTML structure, here is copy paste;
</tr>
</table>
</div>
<tr class="chatline" style="background:white;border-style:none;border-top:1px solid grey;padding:0px;">
you close table and then you do not open it. ctrl + f and type /table. I suggest you just going carefully through it and make valid html ;)
Sorry it is not an answer, but it won't let me comment.
I tried same code in chrome using Dev Tools it is showing me tr and td's, so I am not what is happening in your case. I enclosed above code into html and body tags.
I created a design for my website. I am planning to make it with TABLES because it seems to be the easiest. The tables are not going the way I intended.
There was a problem putting the code on the page so I put my HTML document (.html) and the way I want it to look (.jpg) in the below zip-file link:
http://ericlounge.host22.com/000/22014/0aa.zip
If someone could give me the code or explain my error that would be great!
I would avoid using tables, but it's your choice.
<Table>
<TR>
<TD rowspan ="3">
Navigation
</TD>
<TD>
TITLE
</TD>
<TD rowspan ="3">
SideBar
</TD
</TR>
<TR>
<TD>
ADS
</TD>
</TR>
<TR>
<TD>
Content
</TD>
</TR>
</Table>
This does not answer your question, however, it will give you reasons why you should look at a different approach for your layout/design rather than tables.
Why not use tables for layout in HTML?
To counteract the "tables is the easiest" option then have a look at Yahoo's YUI templates and examples. These can probably produce exactly what you are after with little effort.
