A full example of using reloadDataForRowIndexes to update all rows but only a single column:

int col = 2 ;
[self.myTable reloadDataForRowIndexes:
    [NSIndexSet indexSetWithIndexesInRange:
        NSMakeRange(0,self.myTable.numberOfRows)] 
    columnIndexes:
        [NSIndexSet indexSetWithIndex:col]
];

Or all columns for a single row:

int row = 2 ;
[self.myTable reloadDataForRowIndexes:
    [NSIndexSet indexSetWithIndex:row]
columnIndexes:
    [NSIndexSet indexSetWithIndexesInRange:NSMakeRange(0, self.myTable.numberOfColumns)]
];
