I've tried a few of the options.
Double-click the ui-node-table widget and use the Format option.
For example, if you change the format for the third column (of your screen-shot) to 'color' it will turn these cells 'red' (if you have the text "red" in the object).
Tick and cross seem to react to "0" and "1" or 0 and 1.
I've also got 'Link' to work with.. http://some_web_address
'Row number' does just that - puts a number in the cell to indicate the row of the table.
I'm sure the author will create some example-text before too long.
