How can I add rows and columns to my draw.io tables?

I like to add another column to my draw.io table, how can I achieve this?

Hi there. Adding rows and columns is quite easy. First, select any cell of the row or column that you want to alter. Now go to the grey toolbar and click on the table icon. Once you have a table cell selected, the table icon will expand a menu to either add or remove rows and columns. Alternatively, you will find the same menu in your format panel on the right when you go to the tab Arrange.
