I'm having trouble accessing a declaratively created datagrid by ID, so that I can set its datastore.
Here's my code, but tree is coming back as undefined.
Thanks in advance for any help.

require(["dijit/registry", "dojo/data/ItemFileReadStore"], function( Registry, ReadStore ) {

var tree = Registry.byId("myTree");

});
</script>

Your code has several issues leading to your problem.
dataType is not a thing; you want data-dojo-type (you're probably confusing it with the deprecated dojoType)
Setting data-dojo-id creates a global variable, not an ID for Dijit's registry; set id instead
You're never actually running dojo/parser on the document, either, so even with these issues addressed, you won't end up with an actual widget
Here is a fixed example:
<body>
<table id="myTree" data-dojo-type="dojox/grid/TreeGrid" summary="This is a test">
...
</table>
</body>
<script>
require([
"dojo/parser",
"dijit/registry",
"dojo/data/ItemFileReadStore",
"dojox/grid/TreeGrid"
], function(parser, registry, ReadStore) {
parser.parse();
//var store = new ReadStore(...);
var tree = registry.byId("myTree");
console.log(tree);
// tree.setStore( store );
});
</script>

I have an existing HTML table. I'd like a thin JS library to add simple search and sorting. GridJS looks promising, but I don't understand the docs for loading from HTML. For example, I'm unable to use the useRef function. Even the first line of code in the example fails for me:
>>> gridjs.useRef(null)
Uncaught TypeError: Bt is undefined
Preact 3
<anonymous> debugger eval code:1
Here is a minimal example:
<html>
<head>
<link href='https://unpkg.com/gridjs/dist/theme/mermaid.min.css' rel='stylesheet'>
<script src="https://cdn.jsdelivr.net/npm/gridjs/dist/gridjs.umd.js"></script>
</head>
<body>
<table id='table'>
<tr>
<td>Foo</td>
<td>Bar</td>
<td>Baz</td>
</tr>
</table>
<script>
window.onload = function() {
var node = document.getElementById('table');
new gridjs.Grid({'from': node});
}
</script>
</body>
</html>
I get the error
Uncaught TypeError: t.querySelector(...) is null

I know this answer comes a bit late, but I hope it helps future visitors.
It looks like you still need to call the render function, and the way it seems to work is it hides the table in the DOM and injects the Grid.js table into the wrapper you specify.
For example, this worked for me:
new gridjs.Grid({
from: document.getElementById('mySourceTable'),
}).render(document.getElementById('myDestinationWrapper'));
Lastly, I think thead & tbody is needed - the documentation shows these elements as well: From HTML Table
Here's a snippet as a demo:
document.addEventListener("DOMContentLoaded", function() {
new gridjs.Grid({
from: document.getElementById('sourceTable')
}).render(document.getElementById('destinationWrapper'));
});

I am using a asp.net mvc web app. I have created a table and now I am wanting to use the plugin in datatables. I saw you only needed 3 lines of code to make this work. I attempted to do exactly what it required in order for it to work and give me the desired datatable, but it does not give me the table I am expecting. I even went to examples -> HTML (DOM) source data -> and under Javascript tab I entered the lines required.
Is there something I am doing incorrect here with the script tags or is the plug in just not working? I do not have the files downloaded and imported to my project.
Expecting a standard look like this
But am getting this... so I am missing the look of the datatable plugin and the following Error.
Cannot set properties of undefined (setting '_DT_CellIndex')
my view:
#model List<Fright>
#{
ViewData["Title"] = "Home Page";
var result = Model.GroupBy(gb => gb.Value);

Your problem is a mismatch in the number of <td> </td>. You are just rendering 1 <td> in foreach loop but you have two <th></th> in the table header
#model List<Fright>
#{
ViewData["Title"] = "Home Page";
var result = Model.GroupBy(gb => gb.Value);

I want tableRow.html to be drawn under the table head but the ng-repeat is not drawing at all and the examples are above the table head. If I drop the row with examples directly into the proper location in index.html it will draw just fine. What am I doing wrong?

app.controller('TestController', ['$http', function($http) {

table.rows = [];
$http.get('/item.json').success(function(data){
table.rows = [{"name":"Captain","rate":"0.8910","inverce":"1.1223"}]; //I added this here so I know I am getting json data
});

app.directive('testDirective', function(){
return {

tableRow.html
<tr ng-repeat='row in TestController.table.rows'>
<td>{{row.name}}</td>
<td>{{row.rate}}</td>
<td>{{row.inverse}}</td>
</tr>
<tr>
<td>Example 1</td>
<td>Example 2</td>
<td>Example 3</td>
</tr>
Replace <tr ng-repeat='row in TestController.table.rows'> with
<tr ng-repeat='row in TestController.rows'>
In your controller you're setting table = this, so table.rows actually is this.rows and thus available to the markup via TestController.rows
I am choosing to answer this question:
Also the tutorial I followed on codeschool wraps angular.module within a function but I see that most other examples don't. What is the difference? Why choose one over the other?
This is called an immediately invoked function expression or (IIFE). It is a light-weight way to introduce modules into JavaScript. The goal of using something like this is to ensure lexical scoping of all variables declared at the top level of the module. Without something like this, it is easy to accidentally introduce global variables, which in general is a baaaaad thing.
I'm very frustrated trying to insert and show a JSON within a table. I'm using jQuery DataTable to do it.
I have the following jQuery and HTML code but without success:
<table id="sectorsTable">
<thead>
<tr>
<th><b>Numero</b></th>
<th><b>Nombre</b></th>
</tr>
</thead>
<tbody>
</tbody>
</table>
<script>
var jsonArray = { layersSelected: temporaryArraySectors };
var jsonString = JSON.stringify(jsonArray, null, 2);
$('#sectorsTable').dataTable({
'ajax': jsonString
});
</script>
By the way, the content of the vars is:
temporaryArraySectors = [ [19,"Cordillera"], [10,"Guaiquillo"], [34,"Zapallar"], [27,"Rural Poniente"], [1,"Aguas Negras"], [24,"La Obra"], [28,"Rural Sur"] ];
jsonString = '{"layersSelected": [ [19,"Cordillera"], [10,"Guaiquillo"], [34,"Zapallar"], [27,"Rural Poniente"], [1,"Aguas Negras"], [24,"La Obra"], [28,"Rural Sur"] ] }';
What is wrong?
You don't need to create JSON string with JSON.stringify, just set data option equal to temporaryArraySectors.
See example below for code and demonstration.
$(document).ready(function() {
var temporaryArraySectors = [ [19,"Cordillera"], [10,"Guaiquillo"], [34,"Zapallar"], [27,"Rural Poniente"], [1,"Aguas Negras"], [24,"La Obra"], [28,"Rural Sur"] ];
var table = $('#sectorsTable').DataTable({
data: temporaryArraySectors
});
});

The header 'Speedruns' keeps getting repeated. How can I fix this?
Also, if there is a better way to do this please let me know.

Attached a plunker with the code in it.
Plunker
The thing you want to repeat is the tr, so put your repeat on there. At the moment you are repeating whole the table. The following should work:
<table class="table-size" >
<tr>
<th class="text-center" colspan="2">Speedruns</th>
</tr>
<tr ng-repeat="chan in data0.channels">
<td class="text-left">{{chan.channel.display_name}}</td>
<td class="text-left">{{chan.channel.current_viewers}}</td>
</tr>
</table>
