OK, here's a tough one. At least, it's tough for me.
Say I have 50 pages of identical tables in Indesign. Each table has a few dozen cells, and I want to flow a giant block of text through specific cells through the whole document - for example, cells 1 > 2 > 10 > 11 > 20 > 24 > 29 on each page, linking from one page to the next.
Now, I could do this pretty easily with plain old text boxes, but I have no idea how to flow text between cells in a table. Given IDCS2's great handling of tables, I imagine this may be possible.
