Strange behaviour with angular ng-repeat - angularjs

In my cshtml view I have the following table:
<table>
<thead>
<tr><th>Test</th></tr>
</thead>
<tbody>
<tr ng-repeat="label in labels">
<td>{{label.id}}</td>
</tr>
</tbody>
And when I view the page and inspect the table element in my browser only the table headings are displayed and no rows. Applying ng-repeat seems to comment out the rows automatically as below:
<table class="ng-scope">
<thead>
<tr><th>Test</th></tr>
</thead>
<tbody>
<!-- ngRepeat: label in labels -->
</tbody>
</table>
when I remove ng-repeat="label in labels" and apply a static value in the row cell the row is not commented and displays just fine.
Does anyone knows what could be causing this behaviour?

Upon compilation angular automatically adds the ngRepeat comment to the HTML, in order to indicate that below this comment, the repeated elements will be displayed.
The reason why your tbody doesn't contain any rows, is because your $scope.labels object is empty.

Colorize function not working after updating 2D Array

I am using a duo of ng-repeat's to create a matrix table, but after updating the data the coloring function (a simple return 'green' if the argument is above 0) stops working.
When I load the first (fake) data the colors work just fine, but after any updates it stops working. When initializing the 2d array it will always load and display properly. I have found no debug errors or problem with the logic.
Jfiddle
UPDATE**: I created a simple function that changes a few values in the 'original' 2D-array and I still face the problem with it not updating colors. I am pretty positive this is an AngularJS problem (shortcoming?) and not an issue with the data itself.
HTML
<!-- MATRIX TABLE -->
<div class="center w80" >
<div id = "MatrixTable2">
<table border="1">
<thead>
<tr>
<th></th> <!-- blank -->
<th ng-repeat="ppp in PlayerIDList">{{ppp.name}}</th>
</tr>
</thead>
<tbody>
<tr width="50px" ng-repeat="row in Matrix" >
<td class="rowlabel">{{PlayerIDList[$index].name}}</td>
<td width="50px" ng-repeat="col in row track by $index" ng-class="::funcGetColorByBool({{col}})">{{col}}</td>
</tr>
</tbody>
</table>
</div>
<!-- END MATRIX TABLE -->
I believe your problem is the class binding, the :: prefix means this expression is only evaluated once.
"::funcGetColorByBool({{col}})"
Also, you need to fix your expression to pass in the value of col:
from:
ng-class="::funcGetColorByBool({{col}})"
to:
ng-class="funcGetColorByBool(col)"
Here is a working plunker.

ng-repeat over a div not working

I have used ng-repeat numerous times already in the past, but for some reason I cannot yet understand why it is not on the following situation:
I have an array of objects called registers which I am referencing on the ng-repeat but nothing happens.
I know the array is populated because I have seen it on numerous console.log and because it works if I move the ng-repeat over to the <tbody>
<div ng-repeat = "r in registers">
<!-- START HEADER -->
<tbody class="js-table-sections-header">
<tr>
<td class="text-center">
<i class="fa fa-angle-right"></i>
</td>
<td class="font-w600">Denise Watson</td>
</tr>
</tbody> <!-- END HEADER -->
<tbody>
<tr>
<td class="text-center"></td>
<td>
<!-- Summernote Container -->
<div class="js-summernote-air">
<p>End of air-mode area!</p>
</div>
</td>
</tr>
</tbody>
<!-- END TABLE -->
</div>
I was hoping someone could tell me if there is something I may be ignoring.
Thanks in advance.
I think I just ran into this same problem. It stems from <div> not being a valid elment within a <table>.
I'm guessing that since you have <tbody> there, that there is a <table> tag that was left out of your snippet. <div>s aren't allowed in a table, so the browser moves it before the table. In my situation, doing this, causes the angular scope to change so that there was nothing to iterate over. You can verify this by using the developer tools of your browser.
So, my guess is that you probably want to move the ng-repeat onto the <tbody> or <table> tag.
If you want to use ng-repeat in "div" tag means use "span"
inside div tag. instead of using "table" and its sub attributes..
else use your ng-repeat inside "table" or "thead" or "tr" also
it will iterate rows ...
than only ng-repeat will works.

Angularjs smart-table not sorting $index table cells

I have a problem withe the Smart Table AngularJS Sorting, I implemented this on my table as:
The initialized app:
angular.module('myproyApp', ['smart-table'])
The controller side:
$scope.dataList = []; //any json collection with: id, name and description
The view side with st-table directive:
<table class="table table-bordered table-striped" st-table="dataRows" st-safe-src="dataList">
<thead>
<tr>
<th><span class="glyphicon"></span>Q</th>
<th st-sort="name">Name</th>
<th st-sort="descripcion">Description</th>
<th>Actions</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="row in dataRows">
<td class="col-md-1">{{$index + 1}}</td>
<td class="col-md-4">{{row.name}}</td>
<td class="col-md-4">{{row.description}}</td>
<td>Change</td>
</tr>
</tbody>
</table>
On click the sorting header's cells the table is sorting, but the sorting isn't working for the $index cells. Please if you have any think to include the $index cells to sort. I want not to use the indexes on dataList $scope values, I need that this index will be include only on table view.
Track by is used to link your data with the DOM generation made by ng-repeat. When you add track by you tell angular to generate a single DOM element per data object in the given collection. Because $index has to do with the DOM there is no way to have it relate to a particular data entry. Here's a more detailed explanation.
If you really want to do it without touching your dataList, you could call indexOf in your table:
<tbody>
<tr ng-repeat="row in dataList | orderBy:sortField">
<td class="col-md-1">{{dataRows.indexOf(row)}}</td>
<td class="col-md-4">{{row.name}}</td>
<td class="col-md-4">{{row.description}}</td>
<td>Change</td>
</tr>
</tbody>
Where there is a scoped variable called sortField which is a string that is the name of the field you wish to sort by. I implemented a similar thing in this plunker, using the smart-tables module. http://plnkr.co/edit/AF90dQ
I would advise against this because it quickly becomes expensive for large arrays, and runs into problems if your entries aren't unique.

table with ng-repeat not displaying correctly

Folks I am using a simple ng-repeat directive to display data in table.
However when the directive renders, the first column takes up all the space and dis-figures the table.
Take a look at the plnkr here :
http://plnkr.co/edit/Hahh4uyQ130zOS8noC3D
please focus on the file layout.html
<table>
<thead>
<tr ng-repeat="element in header" class="header-cells" style="width:{{element.width}}px">
<th drop-down-sort-menu>{{element.column}}</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="element in body">
<td ng-repeat="h in header" row="{{$parent.$index}}" col="{{$index}}" style="width:{{element.width}}px">{{element[h.column]}}
</td>
</tr>
</tbody>
</table>
I am sure it's something minor. any clues
I believe you problem is that for the headers, you have 4 TRs with only one TH, as opposed to one TR with 4 THs. For this reason, the cells on your headers are not matching the cells on your body.
Do the first ng-repeat at the TH level.
Give it a try and let me know.

angularJS - Repeating tr's in a table, but dynamically adding more rows while looping

Since examples always tell more then just words here is what I would like to do in another language
<tr>
<c:forEach items="${items}" var="item">
<td>...</td>
<td>...</td>
<td>...</td>
<c:if test="${item.showWarning}">
</tr><tr><td colspan="3">${item.warning}</td>
</c:if>
</tr>
So this will loop over a set of items and show some properties of these items. If there is a warning, a new row will be added underneath the current row in which the warning will be shown. However, how can I do this in angularJs? If I put a ng-repeat on the tr, it will stop at the first end tag of tr. I have read on some other threads that this is not very easily done, but how can it be done? And yes, I really do want to use a table. Here is my contrived example with angularjs which is obviously not working as I would like it to. Any pointers how this can be done?
JSBin example with tr-ng-repeat
Currently (1.0.7/1.1.5) you can't output data outside the ng-repeat, but version 1.2(see youtube video AngularJS 1.2 and Beyond at 17:30) will bring the following syntax(adapted to your example):
<tr ng-repeat-start="item in items">
<td>...</td>
<td>...</td>
<td>...</td>
</tr>
<tr ng-repeat-end ng-show="item.showWarning">
<td colspan="3">{{item.warning}}</td>
</tr>
The idea is that whatever is between -start and -end will be repeated including the -end element.
One solution that I can think of is having multiple tbody tags within the same table. Here is a discussion on the use of multiple tbody tags within the same table.
So, for your issue, you could have the following setup:
<table ng-controller="ItemController">
<thead>
<th>Name</th>
<th>Description</th>
<th>warning?</th>
</thead>
<tbody ng-repeat="item in items">
<tr>
<td>{{item.name}}</td>
<td>{{item.description}}</td>
<td>{{item.warning}}</td>
</tr>
<tr ng-show="item.warning">
<td colspan="3" style="text-align: center">Warning !!!</td>
</tr>
</tbody>
</table>
Repeat the table body as many times as there are entries for the table and within it have two rows - one to actually display the row entry and one to be displayed conditionally.
You can repeat over the tbody
<tbody ng-repeat="item in items">
<tr>
<td>{{item.name}}</td>
<td>{{item.description}}</td>
<td>{{item.warning}}</td>
</tr>
<tr ng-show="item.warning">
<td colspan="3">Warning !!!</td>
</tr>
</tbody>
Also you do not need to wrap the ng-show expression in {{}}, you can just use item.warning
