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

image
image.png1213×735 87.6 KB

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 ?

7

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.

我有几个表格想包含在我的论坛中，您的方法非常有效。我已经创建了以下主题组件初始化文件：

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 }
  );
});

我在帖子中使用以下方式加载表格：

[wrap=dataTables]
<table></table>
[/wrap]

不过，我希望为每个表格自定义多个方面，但我不确定该如何实现。

例如：

  • 我希望为每个表格使用不同的 Gist ID。这应该很简单，只需向 wrap 传递一个属性，然后通过 elem.children[0].dataset.gist 访问它：

    [wrap=dataTables gist="some_gist_id"]
<table></table>
[/wrap]

  • 但如果我想要多个表格，每个表格在 dataSrc 函数中有不同的处理代码，或者有不同的 column 或 dom 参数呢？

    有没有办法将 JS 配置文件传递给 dataTables.dataTable()？

您是否会为不同的表格使用固定数量的变体，还是每个表格都需要自定义变体？

为每个表格自定义配置。

我目前的做法是创建带有不同配置的辅助 JS 文件，并通过 [wrap] 块中的属性进行选择。然后我执行：

dataTables.dataTable(Object.assign(commonConfig, specificConfig(myAttributes)))

但我很好奇是否有更灵活的解决方案。
