Use table styles to change table appearance.
Just as characters and paragraphs have styles, tables have styles, too (since Word 2002). You can still use paragraph and character styles on the content in your tables, but now you can have a separate style for the table structure — including the borders, shading, formatting for specific parts of the table (such as the heading row or the last cell in the table), and more.
By default, new tables you create in Word have the Table Grid table style applied. Table Grid has one-half point single-line borders on all cells of the table — as well as other formatting, like the default cell margin setting (you'll learn about cell margins later in this lesson). To remove those borders, you can apply a different table style or change the borders directly.
Read on to learn how to apply table styles and use borders and shading.
