Decision Table; should allow to insert and position conditions and conclusions

[PeterHeintz]

I have several potential use cases that would fit to the Decision Table feature.
However I do not use it, because it is so limited by just allowing appending rows.

Adding the possibility to insert rows before existing rows or move existing row, is really a basic feature, which is from my point of view the minimum the make Decision Tables usable at all.
