Turn on print view & then click & hold the square at the top left of the table & then drag the table to the center of the page until you see the alignment guides.
Two things that will help with this.
1) make sure in Preferences, you have selected the option to show guides at object center.
2) if you show rulers (under the view menu). You can click and drag from inside the rulers to make permanent guides on the page.
Remember that 0 on the ruler is Not the top left of the paper when printed, but the printing area, inside of the margins. so if you have 1/2" margins set all the way around and are printing on 8.5x11 paper. You would make a horizontal guide at 5" down and a vertical at 3.75" down.
