Need Toggle Button to hide/unhide rows based on cell value in non concurrent rows

I've looked all over this board and found a bunch of solutions, but none that do exactly what I'm looking for and none that actually worked.
I'm using this as a Project Management Task Tracking tool.

I need to button to toggle hide/view done tasks. Column B is where I check a task as done. I use the Marlet font so when I type the letter 'a' in cell, it looks like a check mark.
Resolving that issue alone would be great!

Ideally, I would also like to set a range of rows for this. I have multiple tables on that page, one table for each project, and I add rows often, and since row on top of each table is the name of project, I can't just select the entire B column.
If this can't be done I'll split them across sheets, but it would be awesome if it could.

Thanks.

Oops, sorry about that. Here it is.

Thank you!!!

No. I don't know how to do any of it. Tried using some of the code I found on this site, but there are none I could find that would have 1 button to toggle view/hide rows based on what is in a cell.

Anyone? Please help!

Thank you, though I'm a bit confused. When I create a button, I see a bunch of macros. Which one should I assign to allow to hide and unhide rows by clicking it?
What I'm trying to do is have one button that says 'Hide Done' and when I click on it, all done rows become hidden and that same button now says 'Unhide Done'. Clicking on it would bring back all done rows.

So sorry about that, I'm not sure I was very clear in my original description. Can you help?

Can anyone please help?
