Max value with date

Thought it would be worth mentioning that the first answer will still have all the original values with an extra column identifying the highest for a product type without further work. I'm adding this in case a new table is wanted that only has those highest values and not the whole original table.

First, add a calculated column to your table that creates the rank per city.

Rank Column

Rank = 
RANKX (
    FILTER(
    'Table',
    'Table'[City] = EARLIER('Table'[City])
    ),
    'Table'[Value],
    ,
    DESC,
    DENSE
)

Now create a new table that selects only each city entry that was ranked 1.

New table that only has cities that were ranked 1

Table2 = 
SELECTCOLUMNS(
    FILTER( 'Table', 'Table'[Rank] = 1),
    "City", 'Table'[City],
    "Value", 'Table'[Value],
    "Date", 'Table'[Date]
)

When you create your table visual now from the values on the new table you will only have the ranked 1st entries.
