Now, an Excel spreadsheet will be inserted where you can do whatever you can do in Excel. If you click outside the table, it will look like a normal table. If you once again double click it, it will become an Excel spreadsheet.
You also determine the number of rows and columns to be showed in this table by dragging horizontally and vertically and diagonally when Excel spreadsheet is shown i.e. when you double clicked it. If you drag the middles / corners when in table mode, it will show the same number of cells and reduce their size. But if you drag middles / corners after double clicking the table, you can reduce the number of cells shown.
