Table Builderis aServiceNow featurethat allows administrators tomodify table structures, configure forms, and manage relationshipswithin a visual interface.
When modifying form layouts inTable Builder, administrators can:
#Add, remove, or rearrange fieldson the form.
#Create new form sectionsto organize fields logically.
#Configure default valuesand field properties.
#Manage related listsand relationships between tables.
Option B (Changing the database schema)is incorrect because modifying form layouts does not require schema changes (though Table Builder can modify schemas, it's not necessary for layout changes).
Option C (Editing system scripts)is incorrect because form layout changes do not require scripting.
Option D (Altering the page header theme)is incorrect because themes affect the UI appearance, not form structure.
