1. When navigating to a specific table and selecting the "Tablets" tab, a list of Datashards appears. It is necessary to add another column: End Range.

• The value is taken from the tableinfo endpoint, field EndOfRangeKeyPrefix.
• If EndOfRangeKeyPrefix is not present in the response, the column is not needed.

2. On the tablet page it is necessary to add another field: End Range.

• The value is taken from the tableinfo endpoint, field EndOfRangeKeyPrefix.
• Only the end of the range is displayed (without the start).
• if there is no EndOfRangeKeyPrefix value than new field should be skipped.
• This task is not as critical as the first one. If implementation is difficult, it can be skipped.
