Setting Width and Height
1. If cells within your table do not have a set width and height, they will expand to accommodate the content they contain within the parameters of the overall table structure. You will see that although this table contains two rows, the left row containing text has expanded to fill the entire table.
2. In order to set a constrained width for this cell, you can right click to pull up the menu options and select Cell and Cell Properties.
3. From the cell properties window, you can enter a pixel width in the top left corner.
4. After clicking 'Okay' you will find that the content in this column will conform to the pixel width you have set.
