Transpose Rows and Columns does not work.
After following the instructions to use the Transpose Rows and Columns instruction, the instruction remains ghosted, so I cannot accomplish the transposition. I clicked a cell in the table, selected the table (bullseye at top left of table), clicked Table and tried to click on Transpose Rows and Columns. It was ghosted, so it was not clickable. What is wrong? What should I do? Am using Numbers 6.0 on an iMac.
