title: Script to calculate a total and then merge cells into one in column 'c' if column 'a' has the same date (Using for timesheet)
body: <p>Column A = Date (so there could be multiple rows for the same day but different times)
  Column B = Time spent (number)
  Column C = Will be the total of all cells in column 'B' if has the same date in column 'A'</p>
  <p>So I'm looking to automatically merge the cells in column C if the date is the same in column 'A' so I have one merged cell with the day total hours using a Google Apps script</p>
  <p>Any help would be much appreciated</p>
