A data table is a collection of data organized in rows and columns. It is similar to a Microsoft® Excel® spreadsheet, but with some important differences that are discussed in How is JMP Different from Excel?. A data table might also contain other information like notes, variables, and scripts. These supplementary items are discussed in later chapters.
Figure  .4 A Data Table
The data grid contains the data arranged in rows and columns. Generally, each row in the data grid is an observation, and the columns (also called variables) give information about the observations. In Figure  .4, each row corresponds to a test subject, and there are twelve columns of information. Although all twelve columns cannot be shown in the data grid, the Columns panel lists them all. The information given about each test subject includes the time, cell type, treatment, and more. Each column has a header, or name. That name is not part of the table’s total count of rows.
The table panel can contain table variables or table scripts. In Figure  .4, there is one saved script called Model that can automatically re-create an analysis. This table also has a variable named Notes that contains information about the data. Table variables and table scripts are discussed in a later chapter.
