"Tabular" cells?

I've found myself staring at walls of single-line cells, wondering where all my screen space went.

It'd be great to have a tabular cell style to make these sorts of one-liner parameter entries more compact and easy to read - something like an n-row, three-column table where each row is its own Pluto cell, and the columns are | input | output | comments |, like

You can run more than one line with a begin; end block, but it won't display the output from each line.

This seems like a good opportunity to create a macro that converts a block into a more useful format (like the @show macro I've come to know and love for Jupyter...). Perhaps something like

@tabular begin
	τ = 2π  # The real circle constant!
	ω = τ .* f  # Angular frequency
end

Where the macro assigns each statement and returns a formatted markdown table, for example:

md"""
|Input         | Output    | Comments                  |
|:-------------|:----------|:--------------------------|
|τ = 2π        | $(τ)      | The real circle constant! |
|ω = τ .* f    | $(ω)      | Angular frequency         |
"""

Such that the cell renders like:

Input	Output	Comments
τ = 2π	6.283185307179586	The real circle constant!
ω = τ .* f	6283.185307179586	Angular frequency

Some more thought would need to go into number formatting, but this all seems very possible ...at least with my limited understanding of macros.

Smart approach, and easy to imagine doing with minimal modifications to Pluto. The only downside is the cost of updating all the cells that depend on any combination of parameters in the table whenever you update a single parameter, but that's easy enough for a user to avoid by splitting the block into multiple blocks as needed.

This can be done inside Pluto today! With no modifications to Pluto. That's the cool thing about Julia macros!
