Data for a table can be exported either to Excel or as Tab-separated_values. For large tables, a tab-separated values file is generated much faster than an Excel file.
Note that exporting table data exports only the numbers as displayed in the table. That is, if you need all the underlying data you need to export simulation results directly.
You can also export data to Excel to a temporary file and view the data directly in Excel by clicking the View in Excel toolbar button of the tables screen.
