The usual label for this property is padding and should be used in the respective dialogs.
Use "padding" for space inside boxes and "margin" for outside distances.
(CC help and l10n)
"Word 2010 labels the function as 'Internal margin' (dt: 'Innerer Seitenrand'), which is not suited. Selfhtml uses the wording 'padding' (dt: 'Innenabstand') and 'margin' (dt: 'Außenabstand'). 'Spacing to Content (Margin)' could be kept with the small change to not confuse beginners. For wrap it could also be 'Spacing (Margin)'."
Following this suggestion the setting for "Indents & Spacing" could be labeled "Spacing (Padding)". But I think we better use clear terms and let the user lern it.
So here is the competition.
img:vspace - whitespace on top and bottom of an image
img:hspace - whitespace on left and right side of an image
table:cellpadding - space between the cell wall and the cell content
table:cellspacing - space between cells
table:padding - space between the border and the content in a table
table:border-spacing - sets the distance between the borders of adjacent cells
margin - used to generate space around elements
padding - used to generate space around content
Word 2010 / WPS/Kingsoft Writer
Table: Cell Margins (inside box), Cell Spacing (between cells), Distance from surrounding text (around table)
Object Wrapping: Distance from text (around object)
Object Wrapping: Shape and text is separated (around object)
Table: Inside margins in cell (inside box)
Calligra Words: Indent/Spacing section with "Line Spacing" and "Paragraph Space"
(No need to follow what others do, in my opinion. CSS is the mother of all.)
