DataTable object is a way to represent a two-dimensional data array (data arranged in rows and columns) in Salome. Each column groups values expressed in certain measurement units. All columns and rows have titles. Tables can be rarefied, which means that some cells may be empty, without any values.
DataTable object can be created directly, with the usage of a special programming API (this problem lies out of the scope of Salome GUI Help), or imported from properly defined ACSII files.
Tables are not displayed automatically. To view the imported table, right-click on it in the Object Brower and select Show Table in the context menu.
It is also possible to create Table 3D presentation basing on the table data and display it in the VTK viewer.
Another way of exploiting table data is creating curves and displaying them in the Plot 2D viewer. Plot 2D viewer is described in the documentation on GUI module.
