Reading & Writing from a KijiTable:

The KijiTable interface does not directly provide methods to perform I/O on a Kiji table. Read and write operations can be performed using either a {@link KijiTableReader}or a {@link KijiTableWriter}:
```
  final KijiTable table = myKiji.openTable("tableName"); final EntityId myId = table.getEntityId("myRowKey"); final KijiTableReader reader = table.openTableReader(); final KijiTableWriter writer = table.openTableWriter(); // Read some data from a Kiji table using an existing EntityId and KijiDataRequest. final KijiRowData row = reader.get(myId, myDataRequest); // Do things with the row... // Write some data to a new column in the same row. writer.put(myId, "info", "newcolumn", "newvalue"); // Close open connections. reader.close(); writer.close(); table.release();  
```
@see KijiTableReader for more information about reading data from a Kiji table. @see KijiTableWriter for more information about writing data to a Kiji table. @see EntityId for more information about identifying rows with entity ids. @see Kiji for more information about opening a KijiTable instance.

    final KijiTable table = kiji.openTable("row_data_test_table");
    try {
      final KijiTableReader reader = table.openTableReader();
      try {
        final KijiDataRequest dataRequest = KijiDataRequest.builder()
            .addColumns(ColumnsDef.create()
                .addFamily("family"))
            .build();
        final KijiRowData row = reader.get(table.getEntityId("row0"), dataRequest);
        assertEquals(1, row.getValues("family", "qual0").size());
        assertEquals(1, row.getValues("family", "qual1").size());
      } finally {
        reader.close();
      }
    } finally {
      table.release();
    }
  }
