What did you get as the error?

The QTable sorting is not working properly, we have to click 2 times instead of 1 time to invert the sorting order while going from descending to ascending.

What were you expecting?

Going from descending to ascending take only one click, not two.

What steps did you take, to get the error?

Using the test page I click on a sortable column one time, then click a second time. I repeat this step a couple of time and this is not working while going from descending to ascending.

Ordered ascending

I click ONE time on the same column and then nothing is reverted.

I digged a little bit into the code and sometime we get undefined for this.columnToSort on this line

The user needs to also remove sorting. So sorting has 3 stages: none, ascending, descending. Clicking goes from one to the next one.

My fault, sorry. You're right, none is required to cancel the sort I had not thought about it.
Thank you for your time.

I disagree. At least I want to be able to restrict it to two stages. See Windows Explorer: Only two stages.

3 stages for sorting makes server side sorting more complicated.

Added binary-state-sort Boolean prop to QTable in Quasar v0.17.11 which enables 2 stages (ascending, descending) only.
