Adding Tables in JATS Documents
You can use the Insert Table action on the toolbar or from the contextual menu to add a table in a JATS document. This action inserts a simple HTML-type table into your document at the current cursor position. Once inserted, you can edit the structure of the table using the table buttons on the toolbar (or in the contextual menu). For example you can add or remove cells, rows, and columns, or split or join cells. Additional attributes can be used to fine-tune the formatting of your tables by using the Attributes view ( ).
Also, remember that underneath the visual representation, the table is really just XML. If necessary, you can edit the XML directly by switching to Text mode.
