These are paragraph indents. After selecting a cell, you can go to Format paragraph to see the left indent meaurement In your example document, "Real" has a left paragraph indent of 0, the 2nd row is indented 0.03 inches, "demand" is indented 0.1 inches, "consumption is 0.18 inches, Public and fixed are 0.2 inches. These numbers will be different if your Word is set up for metric units. You may define styles to have a particular indent, and then apply the style rather than have everything in the table as "normal"
