What do you want her to do. If you want her to lie in the corner, then toss little treats into the corner to make it attractive. If she knows sit, then once she is in the corner, have her sit. You will need to begin training at a time you are not at the table eating. Use a cue, like "Place", have her sit in the place, treat, treat, treat. Spend five minutes of training her, and another five minutes a half hour before you eat. Treats can easily include her kibble. Big praise for staying in her place. As the days progress, you can make her wait longer and longer between treats.
