there are so many running total solutions out there...
let
lst = List.Buffer(Table.ToRows(your_table)),
res = Table.FromList(
List.Generate(
() => [i = 0, c = lst{0}, s = c{1}],
(x) => x[i] < List.Count(lst),
(x) => [i = x[i] + 1, c = lst{i}, s = x[s] - c{1}],
(x) => x[c] & {x[s]}
),
(x) => x,
{"week", "delivery", "expected"}
)
