When you add new tables to a Table Layout, they will be added at the default size of 111 x 111 pixels.
Tables can be re-sized by clicking and dragging the small icon in the bottom right hand corner of the table graphic.
You may also click and drag anywhere along the right vertical edge of a table graphic to re-size it in only the horizontal direction or anywhere along the bottom edge to re-size it in the vertical direction.
The minimum size of a table when using the Cloud Suite is 110 x 110 pixels. Note that this is larger than the minimum size allowed on the actual till (which has no lower limit). However, it is considered that 110 x 110 is a more sensible lower limit for a table graphic in practical terms. If you import a CRX from the till that contains tables of smaller dimensions, they will still be displayed in the Cloud Floor Planner but the text within them may overflow the boundaries of the table.
