Set markers/points in table borders?

Is there a way to set marker/anchor points on table borders, so that lines that connect to them “magnetize”/snap to them, so that they line up nicely?

I have included an image to assist in asking this question:

Please describe what the table is supposed to show (large paragraphs, concise data such as numbers, pictures, …) and what connecting lines link. Provided your table contents is “simple”, what you’re looking for is easy to achieve with Draw.

The table contents are simple (a few words and small numbers); I will look into draw. Thank you as always.
Will leave question open so others can weigh in.
