Method

doublecomputeVisibleRowsCount(JTable table)
Returns the number of visible rows in the given table. 
return table.getParent().getBounds().getHeight() / table.getRowHeight();
voidensureRowVisible(JTable table, int row)
ensure Row Visible 
Rectangle r = table.getVisibleRect();
Rectangle rMid = table.getCellRect(row, 0, true);
Rectangle rBefore = null;
Rectangle rAfter = null;
if (row < table.getModel().getRowCount() - 1)
    rAfter = table.getCellRect(row + 1, 0, true);
if (row > 0) {
    rBefore = table.getCellRect(row - 1, 0, true);
...
voidensureRowVisible(JTable table, int row)
To make sure the row is visible. 
Rectangle r = table.getVisibleRect();
Rectangle rMid = table.getCellRect(row, 0, true);
Rectangle rBefore = null, rAfter = null;
if (row < table.getModel().getRowCount() - 1)
    rAfter = table.getCellRect(row + 1, 0, true);
if (row > 0)
    rBefore = table.getCellRect(row - 1, 0, true);

...
intgetFirstVisibleRow(JTable p_Table)
get First Visible Row

intgetVisibleRowCount(JTable list)
get Visible Row Count 
Rectangle visibleRect = list.getVisibleRect();
return getTrailingRow(list, visibleRect) - getLeadingRow(list, visibleRect) + 1;
