Adjusting Margins Using Toolbar: Paragraph Versus Tables

I’m finding this confusing. I understand how I can change the left margin size by sliding the control on the toolbar when focus is on a paragraph (set to 5 cm here as shown in the first image). However when I change the focus to a table cell and slide the margin to make it smaller, it still indicates 5 cm, but the left boundary of the table has moved as shown in the second image. I haven’t changed the padding in the cell. So do margin values differ between cells and paragraph text?
According to the online help, the grey area on the ruler is the margin. But this doesn’t appear to be the case for tables and it seems to be the boundary for the left side of a table.
Do page margins even mean anything for tables? In the second image, it’s 3 cm from the edge of the page to the left boundary of the table and then 1 cm padding to the text, the grey area on the ruler just indicating the table boundary, not the margin.

Ah, I see what I’m changing by dragging on the ruler is called “Table spacing”.
