[CSS 2.1] 'margin-...' in properties index

Hello,

in the properties index for CSS 2.1 [1], there are no restrictions for
the 'margin-...' properties in the "Applies to" column. Yet, in "17.5
Visual layout of table contents" [2], it says that "Cells have padding as
well. Internal table elements do not have margins."

Shouldn't there be a note for the 'margin-...' properties in the
properties index that they do not apply to "internal table elements"? Is
being an "internal table element" synonymous with having one of the
'display' property values 'table-row-group', 'table-header-group',
'table-footer-group', 'table-row', 'table-column-group', 'table-column',
'table-cell' set?

If yes, am I correct in assuming that in any table that follows the HTML
table model, <tr> and <td> elements can never have margins set?

Regards, Christian.
