Highlight errors in Gen2 dataflow

[Steve-DataCoura]

In the Power Query interface for Gen2 dataflows there is no way to easily spot errors in the data.  If you've got lots of columns in a table you need to scroll through them and examine the contents to try to find the errors.

Please provide a simple indicator in the UI to address this.

Something like a warning message in the footer of the UI that says "Error in Column(s)".  Then allow the user to hover over this to see a list of columns that have errors.
