Peculiar margin of table

I cannot understand the margin behaviour of a table in a RichText field.

I created a table and fit it to the margin, and the left side of the table was set to the rich text field mark like ‘L’ letter. It is easy to understand.

After that,I changed the table fitting option from ‘fit to margin’ to ‘fit to window’, and the left side of the table was set to the window frame. It is easy to understand, too.

Next, I scrolled the screen in Notes window to the right with the horizontal scrool bar and return the table fitting option from ‘fit to window’ to ‘fit to margin’.

What’s happen?

The left side of the table didn’t be set to the rich test field mark like ‘L’ letter so as it was, but it seems to be set the left side at the same ‘MARGIN’ distance from the window frame before scrolling.

It is very piculiar behaviour.

Why?

I would like to ask you another peculiar behavior about the table as another topic in this website.
