Field parameter slicer to add extra columns in table visual

Additionally, I want these 2 extra columns to show on specific places in the table, 

You can only show them before or after the Field Parameter block.  You cannot mix the two sections.

Hi Millabu 

This isn’t currently possible, as lbendlin  mentioned. Field parameters can only be made visible within their own blocks and cannot be split. Using parameter views may help instead—you can add an extra column to the parameter table to categorize the fields, and a single field can belong to multiple categories.

Hi Millabu ,
As the others mentioned this is not possible out of the box... buuuuuuut you can kind of hack it together. It still won't be the exact solution you need as this requires two slicers (one for each column you want to show/hide in custom positions in the table - thus not very scalable) but it may still work for your current project. Here are the steps:

1. Add a blank column (I called it "blank") to your table. You can do it in Power Query or via DAX calculated column.
2. Create a field parameter that has "blank" and "customer category" columns. When prompted, add a slicer to the page.
3. In the dax code of the parameter table replace the "blank" with " " (This makes it easier to completely hide the column when customer category is not shown.
   
4. In the slicer settings, force single select. Now you can choose whether to show the blank column or the customer category.
5. Add a text box and overlay it on top of the slicer such that the radio buttons are not blocked, but the slicer values are (you can also set the slicer value font color to match your background, making it invisible. In the textbox you can write your own text, for example "Show" and "Hide". "Hide" should be positioned in line with the radio button that shows the blank column, and "Show" with the button that shows the customer category. Format your slicer header/title sensibly so it is clear that this controls the customer category. You can group the slicer and the text box together by selecting both and pressing ctrl+g, and verify in the selection pane that the text box is above the slicer. Here is how it looks: 
6. Repeat steps 2-5 with "customer status". You can use the same blank column you used before, no need to make a second one.
7. Now you should have: 2 field parameters, each with 2 fields (blank and either customer category or customer status) + 2 slicers formatted
8. Create your table visual by dragging in the original columns, as well as each of the field parameter blocks in the desired order. In my example below I put customer category after the data source, and customer status after the leads:
   
9. When the columns are hidden you will see the blank column, you can resize this manually to remove the visual gap it creates between columns
10. Show-hide your two columns as desired:
    

Not the cleanest and I could not figure out a way to make it work with just one slicer, but it does mostly what you want. Let me know if something is not clear or if you run into any issues.

Thank you all dk_dk , lbendlin and danextian for your replies so far! 

So what I am trying to re-create is this that I know has been done before: 

Here is the Field Parameter that was created:

And there is a slicer visual and a table visual in the report, where looking at the Build section the slicer uses the Parameter 3 as value and table uses the same Parameter 3 in columns. 

I see from the Slicer's visual Filters that it has only Customer Lifecycle Status and Customer Category ticked:

And when there are no selections on the slicer, the table's visual Filters looks like this (both Customer Lifecycle Status and Customer Category are ticked but have "0" next to them): 

And when one or both of the slicer values are selected, they show similarly as the rest of the columns:

For some reason I have not been able to re-create this one, but it seems to be possible. So I don't know if I'm just missing some detail...
