When you double click a Calc chart to enter edit mode (gray box around chart), the Formatting toolbar includes a Data Table icon (located to the right of the Data Ranges icon). The only evidence I have of the purpose of the icon is its tooltip.
For me, this icon always seems to be grayed out / unavailable. Am I missing something or is there a circumstance when the icon is available to perform some function? If so, what is that function?
