-    wxRichTextCell is the cell in a table.
+    wxRichTextCell is the cell in a table, in which the user can type. As well as
+    text, it can also contain objects e.g. an image, or even another wxRichTextTable.
+    
+    A cell's appearance can be changed via its associated wxRichTextAttr; for example
+    its size altered or its background colour set. It also has the properties of
+    column- and row-span. By default these are 1, meaning that the cell only spans
+    itself, but can be increased using the SetColspan() and SetRowspan() methods.
+    Attempts to set too large a span are silently truncated to the table edge.
