The TableItem class represents rows in the table.
The parent of a TableItem is the containing Table.
Its constructor:
TableItem(Table parent, int style)
TableItem(Table parent, int style, int index)
Using the second constructor inserts the row at the specified zero-based index.
Passing an index out of range throws an IllegalArgumentException.
No styles apply for TableItem, so you should always pass SWT.NONE.
