Constructors

Constructor	Description
DefaultTableModel(String[] columnNames, Object[][] data)	Constructs a new table with a 2 dimensional array for row/column data

void	addRow(Object... row)	Adds the given row to the table data
int	getColumnCount()	Returns the number of columns in the table
String	getColumnName(int i)	Returns the name of the column at the given offset
int	getRowCount()	Returns the number of rows in the table
Object	getValueAt(int row, int column)	Returns the value of the cell at the given location
void	insertRow(int offset, Object... row)	Inserts the given row to the table data at the given offset

Methods inherited from class AbstractTableModel

getCellType, getMultipleChoiceOptions, getValidationConstraint, getValidator, setValidator

Modifier and Type	Method	Description
Class	getCellType(int row, int column)	Allows the table to hint the class type of a specific cell
String[]	getMultipleChoiceOptions(int row, int column)	Allows the table cell to feature multiple choice for a specific entry
Constraint	getValidationConstraint(int row, int column)	If the cell has a validation constraint it's returned here
Validator	getValidator()	A validator can be defined here so a validation constraint can bind to a table model cell
void	setValidator(Validator validator)	A validator can be defined here so a validation constraint can bind to a table model cell
