Templates save you money: If you use a royalty_free template, it likely costs less than hiring someone to create a custom graphics package for you. You could easily spend hundreds (or possibly thousands) of pounds on a custom motion graphics opening, for example, whereas you can frequently purchase a royalty_free template for under £200. Of course, the royalty_free template isn't as unique as a totally custom template, but it definitely costs less, and you could always customize the royalty_free template to make it more unique for you.
Word also offers built_in table templates that enable you to insert pre_formatted "Quick Tables" into your documents. To insert a table using one of Word's templates, choose Insert > Table > Quick Tables and choose the template you'd like to use from the gallery. When you click on the template, Word will insert the pre_formatted table of your choice.
