Yes, this can be done from your simple table.
A calculation field can return the date for Sunday of the same week as a way to organize your data by week. Summary fields and one row filtered portals can provide daily totals to arrange your data into 6 daily total columns.
You can base your layout on a table of one record for each week or you can use sub summary layout parts on a layout based on your simple cash table that group your records by week to produce one row for each week.
This is called a "cross tab" report.
Thanks! I will do my best to work on it with your suggestions.
