When table widget is inside blockquote the table's drag handler is truncated:

Blockquote has hidden overflow and table has not big enough padding:
.ck-content blockquote {
overflow: hidden;
}
I also think this is annoying. Let's see if we can do anything about that.

It should be easy fix - just need to overwrite https://github.com/ckeditor/ckeditor5-table/blob/master/theme/table.css#L8 with:
.ck-content blockquote .table:first-child {
margin-top: 2em;
}
Or we can do it with addding space equals to the selection handler height (works in Chrome, but I'm not sure if other browsers supports mixing em and px values in calc() ).
.ck-content blockquote .table:first-child {
margin-top: calc( 1em + 16px );
}
but I'm not sure if other browsers supports mixing em and px
AFAIR this should work (I've used calc(100% - 6em) in CKFinder and that worked (AFAIR) so FF/IE8+ should be fine.
鈽濓笍 Percentages and em/px work fine it's true, but mixing px and em or other values it's another story, I'll check it out.
