680761 - margin-top on table-caption with caption-side: left or right is not rendered

Status: NEW

(Core :: Layout: Tables, defect)

Description

[Daniel.S]

Attachment: testcase

I know, this is table related, not specified in a spec and may actually never get specified at all. I'd just like to have a record or reference.

A caption that is positioned to the left or to the right of a table can't have a margin-top (i.e. margin-top is not rendered on such elements).
margin-bottom works.

According to the description of side caption, margin-top was intended to be rendered, see http://fantasai.inkedblade.net/style/discuss/captions/

Bug 659828 will remove the margin-collapsing of such a margin-top because the table/caption model will be updated to CSS 2.1. That should make it easier to fix this issue.

This might be fixed by including the caption top and bottom margin in nsTableOuterFrame

761   case NS_STYLE_CAPTION_SIDE_RIGHT:
762     case NS_STYLE_CAPTION_SIDE_LEFT:
763       aOrigin.y = aInnerMargin.top;
764       switch (GetCaptionVerticalAlign()) {
765         case NS_STYLE_VERTICAL_ALIGN_MIDDLE:
766           aOrigin.y = NS_MAX(0, aInnerMargin.top + ((aInnerSize.height - aCaptionSize.height) / 2));
767           break;
768         case NS_STYLE_VERTICAL_ALIGN_BOTTOM:
769           aOrigin.y = NS_MAX(0, aInnerMargin.top + aInnerSize.height - aCaptionSize.height);
770           break;
771         default:
772           break;
773       }
