Is it possible to control table row height any other way than increasing font size? I need to have a table with space below and above cell text. I tried (h:30). but without any effect.

I need this for a special type of calendar component, so if there are any large size calendar components that would be great. Especially if it supports adding colored dots etc symbols inside certain dates.

Yes, there is a "Row Height" property in the Properties View that you can use to change the table row height. Look it up in this section of the user guide:

OK I found it. My properties window was so small that this property was almost hidden. Thank you.
