Final answer:
To determine how many records a table contains, Tom should look at the Table footer, which typically holds summaries or aggregate information, such as the total record count.The correct option is 2.
Step-by-step explanation:
Tom wants to know at a glance how many records are contained in the current table. To find this information, he should look at the Table footer. The table footer often contains summaries or aggregate information about the data in the table, which can include a count of the total number of records. Depending on the user interface or application, this footer may display the total directly or provide quick tools to ascertain the number of records.
If he is looking at a database table through a user interface of a database management system (DBMS), it's common for the total number of records to be displayed in the footer section. If it's a table in a spreadsheet or a standard table in a document or webpage, the count might need to be manually inserted in the table footer by the user.
