Power Query how to make a Table with multiple values a parameter that uses OR

I have a question regarding Power Query and Tables as parameters for excel.
Right now I can create a table and use it as a parameter for Power query via Drill down.
But I'm unsure how i would proceed with a Table that has multiple values. How can a table be recognized with multiple "values" as a parameter
For example:
I have the following rawdata and parameter tables
Rawdata+parametertables
Now if I wanted to filter after Value2 with a parameter tables I would do a drill down of the parameter tables and load them to excel.
After that I have two tables that I can filter Value2 with an OR Function by 1 and 2
Is it possible to somehow combine this into 1 Table and that it still uses an OR Function to search
Value2
Im asking because I want it to be potentially possible to just add more and more parameters into the table without creating a new table everytime. Basically just copy paste some parameters into the parameter table and be done with it
Thanks for any help in advance
Assuming, you use Parameters only for filtering. There are other ways, but this one looks the best from performance point of view.
You may create Parameters table, so you have such tables:
Note, it's handy to have the same names (Value2) for key column in both tables, otherwise Table.Join will create additional column(s) after merging tables.
Add similar step to filter RawData table:
join = Table.Join(RawData, "Value2", Parameters, "Value2")

Spotfire: how to get the First and last value in a column based on entity and date?

I have a simple table with two entities and values associated with dates.
I want to extract the FIRST and LAST value based on historical dates. In the underlying data table, the dates are not sorted, hence when using FIRST() and LAST(), Spotfire gives incorrect values. What is the best way to solve this?
I tried
First([Value) OVER (Intersect([Category],[Date]))
Sample of the dataset:
If your using a cross table you can use a nested If statement to return the values when date is Min and Max.

How do we create a generic mapping dataflow in datafactory that will dynamically extract data from different tables with different schema?

I am trying to create a azure datafactory mapping dataflow that is generic for all tables. I am going to pass table name, the primary column for join purpose and other columns to be used in groupBy and aggregate functions as parameters to the DF.
parameters to df
I am unable to refernce this parameter in groupBy
Error: DF-AGG-003 - Groupby should reference atleast one column -
MapDrifted1 aggregate(
) ~> Aggregate1,[486 619]
Has anyone tried this scenario? Please help if you have some knowledge on this or if it can be handled in u-sql script.
We need to first lookup your parameter string name from your incoming source data to locate the metadata and assign it.
Just add a Derived Column previous to your Aggregate and it will work. Call the column 'groupbycol' in your Derived Column and use this formula: byName($group1).
In your Agg, select 'groupbycol' as your groupby column.

Adding Columns to Existing DataTable Programatically

Are there any other possible ways to add columns to a data table within Spotfire, besides the method mentioned here: Spotfire add column from python list? I'm asking because the method works for a particular field that I have, except when the values are NULL (obviously cannot perform a join operation on a field, which is NULL).
I was able to solve the issue through creating a calculated column that uses the row IDs to perform the join so the nulls would never interfere with the join.

Spotfire How column reranks when data is limited by expression or filtered?

I have a shapefile in Spotfire and in the tableview of it I have a column displaying DenseRank. For example, if limit data by expression from the full 100 rows in the table to just 30, the DenseRank does not change. How can I perform this task?
Thanks,
Chris
Tableview does not allow dynamic calculations, unless you have a Document Property in the expression, The calculated column expression executes whenever Document Property value chane (or Calculations refreshed), for your scenario I think instead of using filter create a property control with Fixed values (10,20,30...100) or Values from a column (the one you are using to filter data). and use Document Property linked to the Property Control in your Calculated Column Expression .....
I found a workaround to dynamically rank data based on filtering or marking. If you create a data function as simple as "tableout <- tablein" then you can pass the original filtered and/or marked table to a new table. From there, insert calculated column on the new table and it will recalculate each time.
