I use horizontal lines to separate parts of a page or to set off one part from another. In the table for this page, I inserted a horizontal line in the second row. Before doing that, I adjusted the table so that the second row of the table consisted of a single cell. Here's how to do that:

Put some text in the cells of the second row. I found that doing this sometimes helps Composer not to lose track of which part of the table I'm working on.

Right click on the table within the left cell and select Table Properties.

A window should pop up.

I left everything alone on this window except for the part that tells Composer to make the cell span two columns. Click OK when you have that, and your table should look like this:

Now, right click in the right cell and select Delete and Cell.

Your new table should look like this:

Now, you are ready to insert a horizontal line. Click within the center row and delete the dummy text that you put in there earlier. Now click the Horizontal Line  icon in the tool bar above. Your table should look like this now:

The line will expand to fill the cell it's in as you add text or images to the other cells. For example, here is the same table with some text added (actually, you can see the same thing by looking at the top of this page from within Composer):

You can adjust the properties of the horizontal line by right clicking on it.

The properties allow you to change the alignment of the line and its length and thickness.

I went through all the steps above to put a horizontal line in the bottom row of the table, which now looks like this:

With the two tables that I put in the top row previously, the table should look like this:

Now you're ready to see how to insert an image.
