The following buttons deal with table import and export:
-
Load Table
- Pops up the Load Table dialogue
which allows you to load a table into TOPCAT.
If a table is loaded it becomes the new current table.
-
Save Table
- Pops up the Save Table dialogue
which allows you to write out the current
Apparent Table.
-
Duplicate Table
- Adds a new copy of the current Apparent Table
to the list of known tables. This is like loading in the current table
again, except that its apparent characteristics
become the basic characteristics of the copied one, so for instance
whatever is the current row order becomes the natural order of the
new one.
The following buttons display various views of the current table;
these views are described in more details in Appendix A.3.
-
