Using Measures as Columns in PowerBI Table - powerbi

Question

My First Table is like below -
Daily Returns - Table 1 
Date
 BBB
BB
B
AAA
AA
A
HY
2019-07-01
0.02%
-0.02%
0.04%
0.03%
0.03%
0.03%
0.14%
2019-07-02
0.01%
0.00%
-0.02%
0.05%
0.01%
2.07%
0.08%
2019-07-03
0.01%
0.01%
0.01%
0.02%
0.02%
0.03%
0.17%
2019-07-04
0.01%
0.01%
0.01%
0.02%
0.02%

Second Table as below:
Betas - Table 2
 BBB
BB
B
AAA
AA
A
0.16
0.31
0.43
0.67
1.08
1.05
Now, I want to provide the user with an option to select a beta for each column using a slicer option on the dashboard.
Next, I want to have a calculated table as below:
where each cell is calculated using the following example:
Italic highlighted cell = BBB Daily Return - BBB Beta (value selected by the user in the slicer) * HY Daily Return (Daily Returns for the corresponding dates)
Beta Adjusted Daily Returns - Table 3
Date
 BBB
BB
B
AAA
AA
A
HY
2019-07-01
0.02%
-0.02%
0.04%
0.03%
0.03%
0.03%
0.14%
2019-07-02
0.01%
0.00%
-0.02%
0.05%
0.01%
2.07%
0.08%
2019-07-03

0.01%
0.01%
0.01%
0.02%
0.02%
0.03%
0.01%
And I will have another calculated table:
where each cell is calculated as sum of beta adjusted daily returns till that particular date
Beta Adjusted Cumulative Returns - Table 4
Date
 BBB
BB
B
AAA
AA

HY

What I am facing issues with - I need the Beta table to be an user input in slicer form such that the user selects the values of the betas for different parameters which then calculates Tables 3 and 4 and displays them in a visual.
To summarize:
Table 1 is raw data available from the source.
Table 2 needs to be an user selection from a dashboard slicer.
Tables 3 and 4 will be calculated using Table 1 and user-selected values in Table 2.
How can I make this possible in a PowerBI report? Need to understand how Table 3 will be created/coded in particular.
Will be really grateful if someone could help me figure this out! Stuck on this since a long time.
