When one field on a request page is dependent on another field in the table component, UI rules are triggered and the focus (indicated with single light blue boarder lines around the table component) is lost if you click outside the table component. On a request page with the original table component layout, the UI rules are triggered by clicking Done.
In the following example, the Total Effort field references the Total token [REQD.T.CONTACT_INFO.TC.P.HOURS.TOTAL]:
When you stay in the table component (indicated by the light blue board line around the table), the Total Effort field value is not updated.
After you click outside the table component, the Total Effort field value is updated as a result of triggered SQL rule.
