Borders

There is a 'Draw border' icon on the 'Borders' toolbar. When selected your cursor changes to a pencil. If you keep the right key of the mouse depressed a border will be drawn around the outside edge of the dragged area. It's like selecting a range of cells by dragging the mouse, except rather than selecting them, a border is drawn around the edge.

The 'Draw border' tool toggles with 'Draw border grid'. When the grid is selected all of the cells within the dragged area are bordered to create a table effect.

If requires, change the 'Line style' and 'Line color' from the Borders toolbar before you drag the cells, otherwise you get a basic black line.
