Create new rows based on number

  Hi. I was using power query for finding all paginations but for some pages "add table using examples" doesn't work. Somehow I can extract number of reviews. Since every page has 100 comments I can guess how many pages would be.

  I need to create new rows in another table based on total comments devided by 100.

You can refer below m code as well

let
    Source = Table1,
    RowCountAdded = Table.AddColumn(Source, "RowCount", each Number.RoundUp([Reviews]/100 )),
    #"Added Custom" = Table.AddColumn(RowCountAdded, "GeneateRows", each List.Repeat({ [Teams] },[RowCount])),
    #"Expanded GeneateRows" = Table.ExpandListColumn(#"Added Custom", "GeneateRows"),
    #"Grouped Rows" = Table.Group(#"Expanded GeneateRows", {"Teams"}, {{"Count", each _, type table}}),
    #"Added Custom1" = Table.AddColumn(#"Grouped Rows", "Index", each Table.AddIndexColumn([Count],"Index",1)),
    #"Expanded Index" = Table.ExpandTableColumn(#"Added Custom1", "Index", {"Index"}, {"Index.1"}),
    #"Added Custom2" = Table.AddColumn(#"Expanded Index", "Page", each "/" &"teams"&"/"&Text.Lower(
Text.AfterDelimiter(
[Teams]," ") ) & "/comments"&"/"& Number.ToText([Index.1] )),
    #"Removed Other Columns1" = Table.SelectColumns(#"Added Custom2",{"Teams", "Page"})
in
    #"Removed Other Columns1"

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCklNzFVwVNJRMjQyU4rVgQo4AQWMTCwQAs5AAUtjpdhYAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Teams = _t, Reviews = _t]),
    ChangedType = Table.TransformColumnTypes(Source,{{"Reviews", Int64.Type}}),
    Ad_Page = Table.AddColumn(ChangedType, "Page", each List.Transform({"1"..Text.From(Number.IntegerDivide([Reviews], 100)+1)}, (x)=> Text.Combine({ "/teams/", Text.Lower(Text.AfterDelimiter([Teams], " ")), "/comments/", x })), type {text}),
    ExpandedPage = Table.ExpandListColumn(Ad_Page, "Page")
in
    ExpandedPage
