It's all about the relationship first. Many newbie business owners give a proposal to anyone that they think seems interested in their services. That is an easy way to waste your time. Before you submit a proposal, you should have already developed a strong relationship with the buyer and showed the value that you are going to deliver. Your proposal should be a reiteration of that value and relationship and should only be submitted when you know that you are going to make the sale.
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.
