In addition to applying one or more themes to a presentation, PowerPoint provides many predefined Theme Colors, Theme Fonts, and Theme Effects that you can apply separately from your chosen theme.

Tables are visual displays of data arranged in rows and columns. Table cells contain numbers, text, or a combination of numbers and text. Some cells can include images, symbols, links, and other objects. See how to create and modify tables in Word.

Every inserted or created table in a PowerPoint slide uses the color scheme of the presentation theme. It can take hours to customize the table to your liking.
