In addition to @Lucian's answer... you can use Table and Cell Styles as well.

Configure 1 table how you want it to look. Set the type sizes, fonts, colors, borders, headers, footers, etc.

1. Save the various type formatting as Paragraph styles (Header type, cell type, footer type, etc)
2. Save the cell formatting as cell styles (Header cells, body cells, footer cells, ect). When doing this you reference the paragraph styles above. So when a cell style is applied, that paragraph style also gets applied.
3. Lastly, select the entire table and save it as a Table style. Doing this allows you to set what the cell styles should be (and in turn those cell styles set what the paragraph styles should be).

With all this in place, it's then just a matter of selecting a table and clicking the Table Style you've set up.

You can also configure things like minimum row heights, alternate fills/strokes, header duplicating, cell padding etc, here. So, when the style is applied to an unstyled table, it will change to match, just like Paragraph or Character styles do.
