Here is a quick and dirty implementation using CSS:

Never mind. As I've played around with Checkvist more I've discovered how to add Markdown tables as an item and that solves my need perfectly. Thanks.

I think it would be great if I could column align parts of an item. So if I had a list of runs I could column align the Date, Location, Distance, and Time in each row so it's easy to scan down a list.

It's not a really a table because I don't need headers or sorting or stuff.

I just want to see elements of an item aligned vertically.

Week planner, status board, .... lots of scope for this, have 3 votes! I'd also suggest an option to make the columns multi-select or single selection only per item, and not all items would have the checkboxes shown, e.g. only a parent not each child

I'd love an implementation like moo do does it!!! (https://www.moo.do/). You can add as many columns as you like (panes) and shift items easily from one pane to the other. It really adds another dimension to an outliner, as you can use it for a kanban board. (Thanks for the css hack that Kirill posted recently! But a full column implementation would be awesome and increase the possible use-cases (= potential users :) )

Please add columns!!!!! It would make this outliner unstoppable.

Even a simple column implementation would be much appreciated. Like 1 or 2 columns right-justified.

Ecco's column is a folder was very cool way of doing things.

Column please! something like omnioutliner

Columns would be great. If columns were added, it would also bring a whole level of functionality as utilized by Ecco Pro (a 90's Window's outliner/PIM that still to this day has a strong following).

In Ecco, (which is in my opinion the right way to implement this), a "column" is a representation of a "folder". "Items" (e.g. a line in an outline) can be added to any number of folders, thus when the folder is shown items in the folder are shown. Columns can be added to any "view" (e.g. an outline view that Checkvist currently has), and columns can designate the "field" (e.g. a piece of data such as a date, a checkbox, a word, a selection from an enumerated list, etc.) which ties the item into the folder. It's a real powerful way of approaching an outline, having items be a part of folders, and folders being able to be viewed as columns in a standard outline view.
