Just a general question…
I have just gone over Chapter 16 in the manual, during my review–I fully understand tables and their uses, and the use of appending rows to them, but 16.19 is about amending tables–is this mainly for making table use more convenient during writing/testing, when your source code has gotten enormous and you don’t want to have to shift way back up to change entries in the table? I can see how appending rows is useful for the same reason.
