Outer shadow on table “leaks” inside table

[ubercool]

I'm trying to add a drop shadow to a four-column table, and the shadow leaks into certain cells; see the attached screenshot.

Meanwhile, I have a one-column table where the shadow displays perfectly. Does anyone have any idea why this is happening?

By the shape of the "outer" shadow, it is clear, that the white cells are not considered part of the table. Are they transparent?

I filled that row with white, which solved the problem.

However, that still doesn't explain why the other table did not have this bug, even though it uses the same table format with alternating transparent rows. 🙄

The first column of the four-column table looks OK, and you stated earlier that the first (and only) column of the other table looks OK, so it seems to me that the two tables are behaving exactly the same way.

Alternatively to fill the unfilled cells of the alternating rows you can just apply a white fill to the entire table (= 'frame', as in 'text frame'). This will apply colour behind the existing, alternating cell colours.

Transparent cells (cells with no fill) aren't a bug but there are two different options: cell versus frame colours.
(compare: colour options for text paragraphs:  text colour | character background colour | paragraph decoration colour | text frame colour).

A table format can be applied but you still may modify parameters without changing the saved 'table format' definition.

Again compare text: you can have a certain font or colour with a style saved as "body" applied to some text … but you may still change the font or colour of characters or paragraphs without changing the definition of "body" and "body" will still be applied. For text a deviation of an applied saved style gets indicated by a + symbol next to the style name (e.g. in the context toolbar or paragraph panel as "body+"). For table formats this indicating feature does not exist.

Accordingly two tables (or texts) can have the same saved format (or style) applied but may look different. Like saved text styles also the table formats have an option to (re-)apply a format with overriding any local formatting. If you choose this option for your two examples they will appear with same design.

Thanks so much for your extensive answer. To avoid this issue, I have modified the Table Format template to use white fill rows. I'm glad there is an Override Local for tables, too. Thanks again for the tip! 😊
