Answer 1

You need to get the cell bounds for the last row, JTable#getCellRect(int, int, boolean) will return the rectangle bounds of a given cell, so something like;

Rectangle cellBounds = table.getCellRect(table.getRowCount() - 1, 0, true);

Should give you the location of the given cell.

Armed with this information, you simply need to call JComponent#scrollRectToVisible(Rectangle) to request that the given rectangle is made visible.

table.scrollRectToVisible(cellBounds);
