Viewing the attributes of a table is a common task when working with your data in ArcMap. When viewing tables in ArcMap, all the layer and field properties that you have defined will be honored in the Table window . Tables will also respect any definition queries or joins that you have defined.
Spaces and certain characters are not supported in field names. Special characters include hyphens such as in x-coordinate and y-coordinate; parentheses; brackets; and symbols such as $, %, and #. This applies to non-geodatabase data as well.
You can press CTRL+T to open the attribute table of the selected layer or table in the table of contents. Pressing CTRL and double-clicking a layer or table in the table of contents also opens the table. To see a complete list of shortcuts, see Keyboard shortcuts for working with tables.
