What did you get as the error?

See console output and compare column __index in originalData with table data.

What were you expecting?

__index property not change.

Comment

I found this problem when compare table rows with deep equality for detect user's changes. And found that all rows changed.

How to fix

I not found usage __index property in code. Look like this map call may be removed.

Hi,

The __index prop is a helper. Helps to know at which index within your data you are. Useful (and just giving out a random example) for when using slots and you want to add a button to remove the row (you need to know at which index to remove).

I'm binding QTable data to Vuex and I get warnings about state being modified directly. I tracked it down to __index being added to the data.

Is it possible to stop this from happening?

Removed the addition of this property. The change will be available in "quasar" v1.4.4.

This is my exact use case, and now it breaks after I upgraded quasar. :(

@rstoenescu Is there any alternative to get index inside slot?

Thanks
