I'm creating my program on w3school which it does not provide any debugging tools at all, I basically finished my project on there but later found out I had 80+ errors that needs fixing which I'm given super generic answers so I can't seem to figure out what exactly the issue is. I'm a super newbie at HTML and unlike java where eclipse at least tells you where exactly the error is at and gives you a little better info I have no idea what the errors mean. I am also using w3school file upload method to debug my program. Also my program is basically just a tv schedule having the days, time, and each shows broken down
I've tried googling some answers but its not really helping

I only get these types of errors,
-document type does not allow element "table" here
-document type does not allow element "th" here
You are missing the head and body tags. You need those for valid html. Your table must be contained in the body tag.
<html>
<head>
</head>
<body>
<table>
<!--All your table stuff-->
</table>
</body>
</html>
Also make sure you have all your closing tags. I noticed some missing </th> tags.
UPDATE: The xmlns attribute is required in XHTML, which you are using. You need to add said attribute to your html tag:
<html xmlns="http://www.w3.org/1999/xhtml">
<!--head,body,etc-->
</html>
This can be found on w3Schools
The source of most of the problems you're facing is missing tags. When writing in any markup or programming language, make sure you have the same number of opening tags/braces/groupings as you do closing groupings at the same time as you go along. This problem can otherwise be harder to spot in code and can have some of the worst results.

A table on my site has been flagged by an accessibility plugin (aXe). After some tinkering, it ended up saying that I had to fix the following two things:
<th> elements should only be used when there is a single row and
single column of headers
Table has cells whose rowspan attribute is not equal to 1
How can I reasonably build a table with nested levels of information without violating at least one of those?
My table code is:
<table>
<tbody>
<tr>
<th scope="col" rowspan="2">Type Of</th>
<th scope="col" colspan="2">Blue</th>
<th scope="col" colspan="2">Green</th>
</tr>
<tr>
<td scope="col" class="centered">Light Blue</td>
<td scope="col" class="centered">Dark Blue</td>
<td scope="col" class="centered">Light Green</td>
<td scope="col" class="centered">Dark Green</td>
</tr>
<tr>
<th scope="row">Type 1</th>
<td class="centered">Y</td>
<td class="centered">Y</td>
<td class="centered">Y</td>
<td class="centered">N</td>
</tr>
<tr>
<th scope="row">Type 2</th>
<td class="centered">Y</td>
<td class="centered">Y</td>
<td class="centered">Y</td>
<td class="centered">N</td>
</tr>
<tr>
<th scope="row">Type 3</th>
<td class="centered">Y</td>
<td class="centered">Y</td>
<td class="centered">Y</td>
<td class="centered">N</td>
</tr>
</tbody>
</table>
Accessibility tools are free to invent their own rules, but this tool is wrong saying you should remove table headers th when you use rowspan or colspan. It's totally wrong. Check that you have the last version of this tool : this is an awful advice.
In your case, you can use the following technique to mark column headers:
H43: Using id and headers attributes to associate data cells with header cells in data tables
Your have one problem in your example:
Your headers in your second line are not marked as column headers (th) (and headers attribute should only reference th with id).
You markup should be something like:
<table>
<thead>
<tr>
<th rowspan="2" id="typeof">Type Of</th>
<th colspan="2" id="blue">Blue</th>
<th colspan="2" id="green">Green</th>
</tr>
<tr>
<th id="lightblue">Light</th>
<th id="darkblue">Dark</th>
<th id="lightgreen">Light</th>
<th id="darkgreen">Dark</th>
</tr>
</thead>
<tbody>
<tr>
<th id="type1" headers="typeof">Type 1</th>
<td headers="type1 lightblue" title="Yes">Y</td>
<td headers="type1 darkblue" title="Yes">Y</td>
<td headers="type1 lightgreen" title="Yes">Y</td>
<td headers="type1 darkgreen" title="No">N</td>
</tr>
<tr>
<th id="type2" headers="typeof">Type 2</th>
<td headers="type2 lightblue" title="Yes">Y</td>
<td headers="type2 darkblue" title="Yes">Y</td>
<td headers="type2 lightgreen" title="Yes">Y</td>
<td headers="type2 darkgreen" title="No">N</td>
</tr>
<tr>
<th id="type3" headers="typeof">Type 3</th>
<td headers="type3 lightblue" title="Yes">Y</td>
<td headers="type3 darkblue" title="Yes">Y</td>
<td headers="type3 lightgreen" title="Yes">Y</td>
<td headers="type3 darkgreen" title="No">N</td>
</tr>
</tbody>
</table>
Also, I added a title attribute in order to add a speakable alternative for screen readers (you could have used aria-label but title adds a tooltip for other people, except it is not keyboard friendly). Better choice would be to have here a full word.
I'm not sure what tool you are using, but have you tried using col and colgroup elements? There is some basic information here from W3C about irregular headers in data tables.
Also, I put together a quick JSFiddle based on your table if you want to look at that: https://jsfiddle.net/dngvc84o/
So I got a smart-table, which gets the data from a REST service and displays it. When I try to add pagination the application show errors in the html code, saying all attributes needed on pagination are not allowed there.
Here is my actual code for the table:
<table id="mytable" st-safe-src="dataSet" st-table="displayed" class="table table-responsive portlet-body panel-body">
<thead>
<tr >
<th >A COLUMN</th>
<th >A COLUMN</th>
<th >A COLUMN</th>
<th >A COLUMN</th>
<th >A COLUMN</th>
</tr>
</thead>
<tbody data-ng-dblclick="scrollTo()">
<tr data-ng-repeat="row in displayed" st-select-row="row" st-select-mode="single" data-ng-click="$parent.setClickedRow($index)" and data-ng-class="{'selected':$index == $parent.selectedRow}">
<td data-ng-click="$parent.selData(row);">{{$index}}</td>
<td data-ng-click="$parent.selData(row);">{{row.asd}}</td>
<td data-ng-click="$parent.selData(row);">{{row.dsa}}</td>
<td data-ng-click="$parent.selData(row);">{{row.qwe}}</td>
<td data-ng-click="$parent.selData(row);">{{row.ewq}}</td>
</tr>
</tbody>
<tfoot>
<tr>
<td colspan="5" class="text-center">
<div st-pagination="" st-items-by-page="20" st-displayed-pages="7"></div>
</td>
</tr>
</tfoot>
</table>
After tons of changes finally I made it work, I post the table code if someone needs it.
<div class="smart-table-container">
<table id="mytable" st-safe-src="dataSet" st-table="displayed" class="smart-table table">
<thead>
<tr >
<th >A COLUMN</th>
<th >A COLUMN</th>
<th >A COLUMN</th>
<th >A COLUMN</th>
<th >A COLUMN</th>
</tr>
</thead>
<tbody data-ng-dblclick="scrollTo()">
<tr data-ng-repeat="row in displayed" st-select-row="row" st-select-mode="single" data-ng-click="$parent.setClickedRow($index)" and data-ng-class="{'selected':$index == $parent.selectedRow}">
<td data-ng-click="$parent.selData(row);">{{$index}}</td>
<td data-ng-click="$parent.selData(row);">{{row.asd}}</td>
<td data-ng-click="$parent.selData(row);">{{row.dsa}}</td>
<td data-ng-click="$parent.selData(row);">{{row.qwe}}</td>
<td data-ng-click="$parent.selData(row);">{{row.ewq}}</td>
</tr>
</tbody>
<tfoot>
<tr>
<td class="text-center" st-pagination="" st-items-by-page="5" colspan="8">
</td>
</tr>
</tfoot>
</table>
</div>
While using st-safe-src . The repeater should be on st-table not on st-safe-src.
Pagination works fine then.
if you have only one page in your dataset, the pagination will not show. how many items itemList does have ?
Please try with more items; worked for me.
I am following the UN's accessibility guidelines to write accessible table.
I have this table. I made what -I think- should be a <th> bold.
This is the HTML:
<table width="100%">
<thead>
<tr>
<th>Year</th>
<th>1991</th>
<th>1995</th>
<th>2000</th>
<th>2002</th>
<th>2007</th>
</tr>
</htead>
<tbody>
<tr>
<th>Indicator 1</th>
<td>3.0</td>
<td>11.0</td>
<td>7.8</td>
<td>4.0</td>
<td>4.7</td>
</tr>
<tr>
<th>Indicator 2</th>
<td>9.0</td>
<td>23.4</td>
<td>19.5</td>
<td>9.4</td>
<td>9.1</td>
</tr>
<tr>
<th>Indicator 3</th>
<td>18.7</td>
<td>32.0</td>
<td>30.0</td>
<td>20.1</td>
<td>21.8</td>
</tr>
</tbody>
</table>
But I am not sure it is accurate. I think this makes more sense:
<table>
<tbody>
<tr>
<th id="year">Year</th>
<td headers="year" id="year-1991">1991</td>
<td headers="year" id="year-1995">1995</td>
<td headers="year" id="year-2000">2000</td>
<td headers="year" id="year-2002">2002</td>
<td headers="year" id="year-2007">2007</td>

<th id="indicator-1">Indicator 1</th>
<td headers="indicator-1 year-1991">3.0</td>
<td headers="indicator-1 year-1995">11.0</td>
<td headers="indicator-1 year-2000">7.8</td>
<td headers="indicator-1 year-2002">4.0</td>
<td headers="indicator-1 year-2007">4.7</td>
</tr>
<tr>
<th id="indicator-2">Indicator 2</th>
<td headers="indicator-2 year-1991">9.0</td>
<td headers="indicator-2 year-1995">23.4</td>
<td headers="indicator-2 year-2000">19.5</td>
<td headers="indicator-2 year-2002">9.4</td>
<td headers="indicator-2 year-2007">9.1</td>
</tr>
<tr>
<th id="indicator-3">Indicator 3</th>
<td headers="indicator-3 year-1991">18.7</td>
<td headers="indicator-3 year-1995">32.0</td>
<td headers="indicator-3 year-2000">30.0</td>
<td headers="indicator-3 year-2002">20.1</td>
<td headers="indicator-3 year-2007">21.8</td>
</tr>
</tbody>
</table>
What do you think? Does anyone have experience with tables and accessibility? Please provide references if possible. Thanks.
Note: I am aware of the summary attribute but I removed it here for simplicity.
For a table with a simple structure like this, your markup (the first, simple version) is sufficient for accessibility. A table with similar structure appears in HTML and XHTML Techniques for WCAG 2.0, item Using table markup to present tabular information, with no extra markup, just th for header cells.
Special techniques may be need for structurally more complicated tables.
However, a data table should normally have a caption element for accessibility and usability. It helps the user get key information about the table as a whole. Instead of a caption, a heading or just text before the table could be used for the purpose, but they do not associate with the table (at the markup level) the same way.
I found that using the scope attribute makes more sense:
<table width="100%">
<thead>
<tr>
<th scope="col">Year</th>
<th scope="col">1991</th>
<th scope="col">1995</th>
<th scope="col">2000</th>
<th scope="col">2002</th>
<th scope="col">2007</th>
</tr>
</htead>
<tbody>
<tr>
<th scope="row">Indicator 1</th>
<td>3.0</td>
<td>11.0</td>
<td>7.8</td>
<td>4.0</td>
<td>4.7</td>
</tr>
<tr>
<th scope="row">Indicator 2</th>
<td>9.0</td>
<td>23.4</td>
<td>19.5</td>
<td>9.4</td>
<td>9.1</td>
</tr>
<tr>
<th scope="row">Indicator 3</th>
<td>18.7</td>
<td>32.0</td>
<td>30.0</td>
<td>20.1</td>
<td>21.8</td>
</tr>
</tbody>

This should give me four DIVS inside a container DIV. Here's what it's coming out as:
The correct blocks above the non-inline blocks are from a table with the same exact widths as the ones I'm using on the Divs. There isn't any CSS adding pixels to them, I don't think. I need to line these up, and I can't figure out where my problem is here.
You can use instead of divs the colspan="[number]", for example:
<table cellspacing="0" cellpadding="4" border="0" style="border-width:0px;width:100%;border-collapse:collapse;font-size:12px;">
<tr>
<td colspan="6"></td>

Hoped i helped you.. =)
Width: 100% on the table overrides individual column widths. In your table, there are 13 <th>, and each will have a width of 1/13:th of the table's width. A width property on a <th> doesn't do anything. You could force it by adding display: inline-block to the <th>, but I wouldn't want to go that way.
Also, you should set the pink and green divs to float: right in order to remove the white inbetween green and blue (note however that you'll have to change the order of the divs in your code).
Also, I'd suggest using a table instead if you're aiming to present tabular data.
Did you put cellspacing="0" cellpadding="0" on the table? If not, that might be where the difference is coming from.
Or maybe border.
Can you include the table header?
