There are a number of downsides with the method I explained in the post, too, of course (besides the extra work). Such as, the cells that are “threaded” have to be the same width, since you can’t make unequal columns in a single text frame. And resizing the table’s rows and columns often means you have to manually adjust the size of the anchored frame.

Also, although you can select the text frame with the Selection tool and see the inport and outport boxes, they’re non-functional. So you can’t thread one anchored text frame to another (whether they’re anchored in a table cell or elsewhere), which would be cool.
