Best bet is to use the scale in the Status Bar (near the bottom-right of the screen) to change scales. Make sure this setting is the same in your viewport as it is in modelspace when you first create your table.
For example, if you have modelspace set to 1" = 50' when you create the table, set the viewport to 1" = 50'. I like having dedicated viewports for these tables, containing nothing but the tables, while the linework is all in a separate viewport.
