This week we have rolled out a number of table block improvements, including: 

4 adjustable row heights 
Choose from 4 row height options, including small, medium, large & extra-large. The smaller the row height the more records you can show at once on your table. The larger the row heights allow you to show more information per field. Alternatively, toggle on our auto switch and we will adjust the row heights based on the amount of information within the table.  

Adjustable column widths
You can now define the default width of a column by selecting the block and hovering your cursor over the edges of the column title until the handle option appears. You can then simply drag to your desired width and the changes will be reflected within the application. Please note - to edit the column widths you need to access preview or via your published application.
