Searching for interactive frontend list / table solution with direct input

I need something quite simple for a little team site I administer (private kindergarten) and I didn’t find anything usable so far, maybe someone in this forum can point me to the right track.

Thing needed:
I want to display a very basic but editable table on a page (only accessible by logged-in users). It should be like a simple list like those you put on a pinboard, with a header, at least two columns and multiple rows. Like, imagine a party and everybody should enter some food to bring along:

Name – Food to bring
Alex – tomato salad
Ben – chips
Beth – muffins

etc.

I want my users to be able to enter items directly to the list from the frontend. Additional edit / delete buttons would be perfect.

I didn’t find any simple plugin to accomplish this and I really don’t need a fancy database manager with sort and stuff. It should be more like these tiny poll tools but with custom input. Ah and I don’t want to embed google spreadsheets or something… Does anybody know a plugin which could fit my needs?

If not, could anybody give me feedback on this plan:

– create a custom post type (“members list”)
– add columns via custom field input -> creates the header of the table (comma separated, like “Name, Food to bring” = 2 columns)
– use a function (which one?) to create and post to a custom db table according to the columns
– add corresponding input fields
– fetch and display the updated list after form submit
– bonus: add edit / delete functionality

I’m not a coder at all but I sometimes manage to pick the right pieces together to make something work. But this time I think it’s too complex. Could anybody give me some guidance / examples / tips how to move forward?

Would be really great! Big smile great 🙂

Thanks
