The goal is, eventually, in the planner, to also show the calculated waypoints for deco stops. So far, the calculated deco is only output via qDebug() to the console.

Hello Robert, while trying to achieve this task, I am facing few
problems, can you guide me in case I am going wrong somewhere.

To direct this info to UI, we have two choices as you mentioned,
either create extra table or update new columns in existing
tableWidget (Dive Planner Points). However due to the space
limitation, I tried to add extra columns in the "tableWidget". For
this case, we must emit dataChange signal after each edit (either via
table or diveplannergraphics) to update all columns including the
extra columns created for the purpose of showing "computed time" and
"computed depth". From the code, it looks like "dive plan" is computed
within the drawProfile() call, and this assumes, data to be read from
tableWidget and draw the contents. For extra column case, it looks
like I must call "editSlot" after creating dive plan, which is done in
the drawProfile method. So, as a sanity check I tried to call
"editSlot" in the "for" loop of "drawProfile" where subsurface is
drawing polygon on the graphics window.

It looks like, clearly I am missing many crucial things, in case its
not a trouble can you give me a hint of the work flow that I need to
be aware of, in this case.
