Hello Community,
Did anyone try to embed Data tables into Topic Body ? Any plugin or theme ?
Thanks,

I tried making tables with a some links to images within a cell and failed. See: How to make a nice table in a post?
So by extension, I don’t think basic Discourse will allow this.
If it is possible I would like to know how.
Since the site I am on can not add more plug-ins per the plan/agreement, I could not run down that option path.

Yeah, I don’t know how to implement this.
Not the full boat, but maybe good enough to get you started.

The above HTML was created by opening link provided (using Chorme), press F12,
select HTML in code viewer
then (Windows) right mouse select Copy -> Copy OutterHTML
and pasted into this post.
I know it doesn’t have all of the bells and whistles of the original, but at least you can compare this HTML with the original and see what Discourse filters out to learn what you can and can not do.
Also if someone with more trust can convert this to a Wiki so others can view the raw HTML it would be appreciated.
HTH
EDIT
Expanding on cutting and pasting, I cut the full page out and pasted into a post at try.discourse.org to see if the buttons for sorting would make it through. No such luck.

That result is just a Markdown table which is supported by Discourse:

Great. But does it have Data table functionality like sorting, searching ?
No.
My best guess on how to do that would be to use JavaScript, but I don’t know how much of that will be filtered out of Discourse. When I ran into the same line of problems, I eventually came to the conclusion that it would be easier to to put the page with the info somewhere else and provide a link. Don’t try and force Discourse into something it is not, and don’t try and circumvent the security Discourse provides, it is there for a good reason.

That’s true, My best option is adding the datatable in an html page and embed it into Discourse topic using iframe.
Datatables is a jQuery plugin. jQuery plugins can be implemented quite easily in Discourse. There are a couple of examples of this like the Tiles and Slick gallery theme components.
Essentially, what you need to do is to create a decorator for posts that contain tables that you want to target with dataTables.
I’ve created an example of how you can do that here
https://github.com/hnb-ku/dataTables_Demo
and created a preview for it on theme creator here
https://theme-creator.discourse.org/theme/Johani/discourse_datetables
It’s obviously a bit basic for now, and it’s missing some styles but it should be a good starting point as sorting, searching and pagination work just fine.

Ich habe mehrere Tabellen, die ich in mein Forum aufnehmen möchte, und Ihr Ansatz funktioniert perfekt. Ich habe diese Initialisierungsdatei für das Theme-Komponente erstellt:
import { apiInitializer } from 'discourse/lib/api';
import loadScript from 'discourse/lib/load-script';
export default apiInitializer('0.11.1', (api) => {
api.decorateCookedElement(
(elem, helper) => {
const dataTables = $('[data-wrap="dataTables"] table', elem);
if (!dataTables.length) return;
loadScript('https://cdn.datatables.net/1.10.25/js/jquery.dataTables.min.js').then(
() => {
$.fn.dataTable.ext.errMode = 'throw';
dataTables.dataTable({
ajax: {
url:
'https://gist.githubusercontent.com/USERNAME/MY_GIST_ID/raw/data.json',
dataSrc(data) {
return data.map((x) => {
return {
id: x.my_id,
title: `${x.number} - ${x.title}`,
};
});
},
},
columns: [
{ data: 'id', title: 'My ID' },
{ data: 'title', title: 'My Title' }
],
dom: 'Bfrt',
});
}
);
},
{ id: 'discourse-my-custom-data-tables', onlyStream: true }
);
});
Und ich lade die Tabelle im Beitrag so:
[wrap=dataTables]
<table></table>
[/wrap]
Allerdings möchte ich für jede Tabelle mehrere Dinge anpassen und bin mir nicht sicher, wie ich vorgehen soll.
Zum Beispiel:
-
Ich möchte für jede Tabelle eine andere Gist-ID verwenden. Das sollte einfach sein, indem man ein Attribut an das Wrap übergibt und es dann mit
elem.children[0].dataset.gistabruft:[wrap=dataTables gist="some_gist_id"] <table></table> [/wrap] -
Aber was ist, wenn ich mehrere Tabellen möchte, jede mit unterschiedlichem Verarbeitungscode in der
dataSrc-Funktion oder unterschiedlichencolumn- oderdom-Parametern?Gibt es eine Möglichkeit, eine JS-Konfigurationsdatei an
dataTables.dataTable()zu übergeben?

Gibt es eine festgelegte Anzahl von Varianten, die Sie wahrscheinlich für verschiedene Tabellen verwenden würden, oder müssen Sie für jede Tabelle individuelle Varianten erstellen?
1 „Gefällt mir“
Individuelle für jede Tabelle.
Mein aktueller Ansatz besteht darin, Hilfs-JS-Dateien mit unterschiedlichen Konfigurationen zu erstellen und über ein Attribut im [wrap]-Block zwischen ihnen zu wählen. Anschließend führe ich Folgendes aus:
dataTables.dataTable(Object.assign(commonConfig, specificConfig(myAttributes)))
Ich wäre jedoch neugierig zu wissen, ob es eine flexiblere Lösung gibt.
