First, set "I, Title I" by automatic numbering, and then drag the left-aligned tab stop ┗ on the ruler with the left mouse button to adjust the tab stop. If you want to leave a few spaces, you can leave them blank. However, the default tab stop step size for word is two spaces. Therefore, if you need to change the tab stop step to 1 space, you can double-click that tab stop to pop up a dialog box and change the default tab stop from two characters to 1 character.
