[BUG] coloring cell is not working when starting with an invalid or empty data file

[LaurentOngaro]

To reproduce

1. start with en empty or invalid file
   • an empty file will be create and a "fake" table with one fake row will be displayed
2. Valid the dialog to rebuild the data
3. The data are displayed but coloring is not working

Cause

The issue is due to missing keys in the colorRows(self) method used by a Pandastable and by default it raises a KeyError exception

Work Arround

• Override the method colorRows(self) in the EditableTableClass
• Add try except blocs
• Exceptions are now gone

Failed fixes

Coloring is not working anymore, even after a new data rebuild. Application must be restarted to restore coloring

[LaurentOngaro]

To restore initial errors, just change the name of colorRows(self) to use the default version
