How to cite a table that has been significantly modified (see example)?
What you do is create your own table, and not display an existing one in modified form. Thus, I would cite the contents taken from the other publication just like any other source you refer to.
I would suggest the following: indicate the rows of the table taken from the source in any way (e.g. put an asterisk at the end of the rows, make those rows a different color, ...) and at the end of the table add a footnote stating: &quot;information in marked rows taken from [cite source].&quot;
