Calculating the total sum of a column in a prefilled table has been made easy with a sum formula.
To start, navigate your cursor to the left tab and drag the 'Prefilled table' under 'Table'. Prefilled tables allow you to have a fixed number of row, thus making it easier to total the sum of a column.
To sum a range of cells, use the formula:
=SUM(Number1:Number2)
Where Number1 is the start of the range, and Number2 is the end of the range.
Number1, Number2, and the numbers in between will automatically be summed.
For example:
Given that the cells contain these numbers,
A1 = 5
A2 = 10
A3 = 15
A4 = 20
Therefore the formula,
=SUM(A1:A4)
Returns the value, 50.
