To display more of the fields with longer values, you may need to adjust the row height in the grid. To do this, go to:
Your Portal's configuration page
Select Tables on the left
Click on the appropriate table
Views section
Change the Grid row height:
This is either set in the Default View Options, or
Under View Type in the individual views' settings, if they are set to use custom view settings.
Limitation: When setting the grid row height to "fit content", long text, rollup and formula fields will not expand the height of the row.
This option will only appear when the View Type is set to Grid. The default row height is set to Short.
