The instructions of the engineering journal I submitted to (IEEE transactions on wireless communications) says this regarding the final submission of figures and tables
Please upload the Originals (masters) of the tables and figures (in separate files, one figure per file). All graphics material submitted for publication must be original drawn figures in .eps format, with each figure submitted as a separate file. Figures exported from other formats (e.g., PDF, PowerPoint) will not reproduce well in print. Appropriate fonts include: Symbol, Helvetica, Arial, Times New Roman.
What do they mean by "originals (masters) of the tables"? Does it mean that I should submit each table also as a separate file? If so, in which format?
