If you know HTML, this should all work roughly how you would expect. If you are not - familiar with HTML, please read Tables in HTML Documents. Pay attention to TABLE, TR, TD related parts of the document.
- -Table()- - Example -
- t = gui.Table()
-
- t.tr()
- t.td(gui.Label("First Name"), align=-1)
- t.td(gui.Input())
-
- t.tr()
- t.td(gui.Label("Last Name"), align=-1)
- t.td(gui.Input())
