Changing index (ascending/descending) does not update font colors

The following code snippet results in a rather odd behavior when clicking in the top-left cell, which by default is change the index from ascending to descending or vice versa

```
def color_provider(row, column, table):
row = table.values[row]
if column < len(row) - 1:
val = row[column + 1]
if val < 8:
return Color.GREEN
if val > 42:
return Color.RED
return Color.BLACK

def table(df):
table = TableDisplay(df)
table.setStringFormatForTimes(TimeUnit.DAYS)
table.setFontColorProvider(color_provider)
return table
```

For the necessary weird indexing in `color_provider` i opened another issue (#8194)

So, when i change the index, the colored cell simply stays in the same position (when the value obviously changes) in the table, which is really odd because implementing `color_provider` leaves client code with the idea that the color depends on the cells value
