I Am Having Trouble Using Text In Tables

HI, I'm trying to create a table of text in a brochure and when I try to input the text, as you can see from the screenshot, I get this tight text frame around my text which won't expend to the edge of the table cell.  As you can see from the black dots surrounding my text, I'm unable to click-drag them to the edge of the cell.  Just wondering if anyone could assist. Thanks.
