Yes you can do this via using customised CSS for your exact form. The customised CSS is added as a code page in your app and then the CSS template defined in your exact form has to be amended to point towards your custom CSS page.
You can either write your own from scratch defining the style for each element of the quickbase table (note this may take you a while but can be done if your feeling adventurous and have some knowledge of CSS).
Or
You can make a copy of the current quickbase CSS template and edit only the bits you want to change. This involves defining styling for undefined elements (these normally inherit styles unless there is one defined for the element). Where these are defined and your amending the style doesn't work then use !important to force it to apply your style. For example div.tablesearchresults {font-family:Arial !important;} this will force the font to be applied (note this isn't best practice but can be used).
I have previously posted some info on a border less table on an exact form (useful for long lists) which can be found here:
https://quickbase-community.intuit.com/questions/1106249-why-can-t-quickbase-make-exact-forms-more-usefulHere is a grid style table CSS template (this removes the left column but also removes the total):
http://pastie.org/10083018To apply this simply paste the pastie code above into a code page and name the page. for example grid.css
Then in your exact form in the head section find the call referring to the default css template and replace it with this (changing REALM NAME to your realm name and the CODE PAGE TABLE ID to the table id of the main dashboard (i.e click home on the app and take the table id from there):
<link href="
https://REALMNAME.quickbase.com/db/CODE PAGE TABLE ID?act=DBpage&pagename=grid.css" rel="stylesheet" type="text/css">
There are some limitations, such as if quickbase make changes to the id of elements you have defined with your own styles then you will need to update the CSS template to get it to work.
Hope this helps.
