A Table organizes a collection of data into rows and columns, each row containing a data record, and each column containing data values for a named data field with a specific data type. Table data can be accessed directly using the row number and column name, or rows can be treated in an object-oriented fashion using Tuple instances that represent a single row of data in the table. As such, tables implement the TupleSet interface.

Table rows can be inserted or deleted. In any case, none of the other existing table rows are effected by an insertion or deletion. A deleted row simply becomes invalid--any subsequent attempts to access the row either directly or through a pre-existing Tuple instance will result in an exception. However, if news rows are later added to the table, the row number for previously deleted nodes can be reused. In fact, the lower row number currently unused is assigned to the new row. This results in an efficient reuse of the table rows, but carries an important side effect -- rows do not necesarily maintain the order in which they were added once deletions have occurred on the table. If not deletions occur, the ordering of table rows will reflect the order in which rows were added to the table.

Collections of table rows can be accessed using both iterators over the actual row numbers and iterators over the Tuple instances that encapsulate access to that row. Both types of iteration can also be filtered by providing a Predicate, allowing tables to be queried for specific values.

Columns (alternativele referred to as data fields) can be added to the Table using addColumn(String, Class) and a host of similar methods. This method will automatically determine the right kind of backing column instance to use. Furthermore, Table columns can be specified using a Schema instance, which describes the column names, data types, and default values. The Table class also maintains its own internal Schema, which be accessed (in a read-only way) using the getSchema() method.

Tables also support additional structures. The ColumnMetadata class returned by the getMetadata(String) method supports calculation of different statistics for a column, including minimum and maximum values, and the number of unique data values in the column. Index instances can be created and retrieved using the index(String) method and retrieved without triggering creation using getIndex(String) method. An index keeps a sorted collection of all data values in a column, accelerating the creation of filtered iterators by optimizing query calculations and also providing faster computation of many of the ColumnMetadata methods. If you will be issuing a number of queries (i.e., requesting filtered iterators) dependent on the values of a given column, indexing that column may result in a significant performance increase, though at the cost of storing and maintaining the backing index structure.

  - getColumnRow
```
public int getColumnRow(int row,
                        int col)
```
    Get the row value for accessing an underlying Column instance, corresponding to the given table cell. For basic tables this just returns the input row value. However, for tables that inherit data columns from a parent table and present a filtered view on this data, a mapping between the row numbers of the table and the row numbers of the backing data column is needed. In those cases, this method returns the result of that mapping. The method getTableRow(int, int) accesses this map in the reverse direction.
    
    Parameters:
    
    row - the table row to lookup
    
    col - the table column to lookup
    
    Returns:
    
    the column row number for accessing the desired table cell
  - getTableRow
```
public int getTableRow(int colrow,
                       int col)
```
    Get the row number for this table given a row number for a backing data column and the column number for the data column. For basic tables this just returns the column row value. However, for tables that inherit data columns from a parent table and present a filtered view on this data, a mapping between the row numbers of the table and the row numbers of the backing data column is needed. In those cases, this method returns the result of this mapping, in the direction of the backing column rows to the table rows of the cascaded table. The method getColumnRow(int, int) accesses this map in the reverse direction.
    
    Parameters:
    
    colrow - the row of the backing data column
    
    col - the table column to lookup.
    
    Returns:
    
    the table row number for accessing the desired table cell
  - addRow
```
public int addRow()
```
    Add a row to this table. All data columns will be notified and will take on the appropriate default values for the added row.
    
    Returns:
    
    the row number of the newly added row
  - addRows
```
public void addRows(int nrows)
```
    Add a given number of rows to this table. All data columns will be notified and will take on the appropriate default values for the added rows.
    
    Parameters:
    
    nrows - the number of rows to add.
  - updateRowCount
```
protected void updateRowCount()
```
    Internal method that updates the row counts for local data columns.

```
public boolean removeRow(int row)
```
    Removes a row from this table.
    
    Parameters:
    
    row - the row to delete
    
    Returns:
    
    true if the row was successfully deleted, false if the row was already invalid
  - clear
```
public void clear()
```
    Clear this table, removing all rows.

public boolean isValidRow(int row)
```
    Indicates if the given row number corresponds to a valid table row.
    
    Parameters:
