How is the 'table_array' in the VLookup function defined?

The 'table_array' in the VLookup function is defined as the data range containing values. This is critical to understand because the VLookup function searches for a specified value in the first column of this range. The function will then return a value from a specified column within that same row.

For example, if you are searching for a product ID in a table that has multiple columns (such as product information, prices, and stock levels), the 'table_array' would encompass all the columns of that table. By doing so, VLookup can effectively retrieve the desired data based on the lookup value you provide.

Understanding the definition of 'table_array' is essential for effectively using VLookup, as it determines both where the function looks for the lookup value and from which column it retrieves the result. The other options don’t accurately define this parameter, as they relate to different aspects of the VLookup or do not encompass the totality of what 'table_array' represents.
