To access Professional Options and modify the appearance of headers and the data grid (which are used for tables, views, and many reports), select the gear icon 
in the data grid toolbar.
Figure 1 Options Button and Row Levels
•Column Headers: formatting of columns with specific requirements
•Row Appearance: formatting for each row level of the data grid, separated by even and odd rows. Each level refers to further nesting, e.g. of child tables opened within a parent table. Odd row shading for Levels 1, 2, and 3 is shown above in Figure 1.
