|
int | getFirstCategoryIndex()
Returns the index of the first visible category.
|
int | getMaximumCategoryCount()
Returns the maximum category count.
|
int | getRowCount()
Returns the number of rows in the table.
|
int | getRowIndex(Comparable key)
Returns the row index for a given key.

|
Number | getValue(Comparable rowKey, Comparable columnKey)
Returns the value for a pair of keys.
|
Number | getValue(int row, int column)
Returns a value from the table.
|
void | setFirstCategoryIndex(int first)

underlying dataset, and sends a DatasetChangeEvent to all
registered listeners.
