A database or tabular file containing information about a set of geographic features, usually arranged so that each row represents a feature and each column represents one feature attribute. In raster datasets, each row of an attribute table corresponds to a certain zone of cells having the same value. In a GIS, attribute tables are often joined or related to spatial data layers, and the attribute values they contain can be used to find, query, and symbolize features or raster cells.
Add and View Tables
A table can be added to a map the same way any other data is added to a map. To explore the attributes of a layer on a map, open its attribute table to select features and find features with particular attributes. More than one table can be opened at a time. For example, an attribute table for administrative boundaries and the attribute table for cities can be viewed at the same time.
A look into the tabular data
When working with GIS data, every user would have a different data set to work with depending on the application used while performing the task. When the tabular data is viewed in the table window, users can see a user-friendly and customized version of a table. There is also an option to hide fields in the table.
