Answer:
Put the insertion point in the table so you are actively in the table.
Step-by-step explanation:
When it comes to using the "Microsoft Publisher," it is very important to know what elements are under each tab. For example, under the Table Tools tab, you'll be able to see the "Design" and "Layout" tabs.
The "Design tab" will allow you to make your table or edit it (including its borders). It will also allow you to format your table regarding its cells and arrangement. The "Layout tab" will provide you a selection of tools that you will be needing in order to arrange the rows and columns, delete or merge cells, control the alignment of cell margins, etc.
So, in order to view table tools, it is essential that you put your insertion point (the blinking vertical line that you see in your document) in the table so you are actively in the table. The insertion point will direct you to where you are going to actively work.
