How to format table background when page has a background image

[alexj]

Hi,
Not sure if U can explain this without attaching an example but here goes. I have a document with an image set as background (Wrap → In background) . If I then add a table I am able to set the background format of a row (Table → Properties → Background <As Colour As Row>) to an arbitrary colour.

What I see is that where the table overlaps the background image, the background image takes precedent. Where the table is not over the image I see the expected row colour.

Is there something I am missing with regards to background images on pages? I have it set as background and no amount of send-to-front , send-to-back make any difference. What I am seeing implies that the background setting for tables is some special class of background layer that is inaccessible and behind even a background image.

I know this is the case because the opacity setting of the background image works and reveals the table row background format as it is increased.

Is there a way to make the table the foreground and have the background image on the page respect that?

I have a dropbox example of this with an image set to 50% transparency that also happens to have the middle set to transparent in the original image

Insert the table in a frame. The background’s colour won’t overlay the frame’s area’s colour.

I’m not sure but I think this phenomenon is more a bug than a feature.

You’re probably right because table are inserted using an implicit frame. If making it explicit brings the expected behaviour (from user’s point of view), this is a bug (either technical or documentation unforgivable omission)

I just tried it and yes creating an explicit frame and adding a table to that keeps the background where it should be. I must say that I am very impressed with the speed and helpfulness of this forum so thanks again

It seems that same issue also affect background in titles, they are not shown if there is an image set as background. And set titles into frames not seem to be possible, or at least compatible with styles.

The way LO manages watermarks and background is a bit unelegant, would be dessirable a feature that let you set the page background to go through the margin limits.

If another one has a way to set an image as background without cover table-titles-other elements background, I would be pleased to know, but seems that this behaviour is by design.

Thanks a lot
