Hi @DavidNunes7
You can create two blank query and put the following codes to advanced editor in power query
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjIwMta30DdU0oExjSyAbEelWB24pJElTNZS39gAyHZSio0FAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Date Start" = _t, #"Date End" = _t, Text = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Date Start", type date}, {"Date End", type date}, {"Text", type text}}),
#"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each 1)
in
#"Added Custom"
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTIyMDLWt9A3MleK1YlWMkISsVSKjQUA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Id = _t, Date = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Id", Int64.Type}, {"Date", type date}}),
#"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each 1),
#"Merged Queries" = Table.NestedJoin(#"Added Custom", {"Custom"}, Query1, {"Custom"}, "Query1", JoinKind.LeftOuter),
#"Expanded Query1" = Table.ExpandTableColumn(#"Merged Queries", "Query1", {"Date Start", "Date End", "Text"}, {"Date Start", "Date End", "Text"}),
#"Removed Columns" = Table.RemoveColumns(#"Expanded Query1",{"Custom"}),
#"Added Conditional Column" = Table.AddColumn(#"Removed Columns", "Custom", each if [Date] >= [Date Start] and [Date] < [Date End] then 1 else 0),
#"Filtered Rows" = Table.SelectRows(#"Added Conditional Column", each ([Custom] = 1)),
#"Removed Columns1" = Table.RemoveColumns(#"Filtered Rows",{"Date Start", "Date End", "Custom"})
in
#"Removed Columns1"
Output

Tank you a lot!!!!
Hello, @DavidNunes7
let
tblA = your_table_A,
tblB = your_table_B,
tblB_mod = Table.RenameColumns(Table.DuplicateColumn(tblB, "Date", "Date End"), {"Date", "Date Start"}),
a_b = tblB_mod & tblA,
sorted = Table.Sort(a_b,{{"Date Start", Order.Ascending}, {"Date End", Order.Descending}, {"Text", Order.Descending}}),
down = Table.FillDown(sorted,{"Text"}),
flt = Table.SelectRows(down, each ([id] <> null)),
rc = Table.RemoveColumns(flt,{"Date Start"})
in
rc
