Remove a single blank row from a matrix

hi, Anonymous 

To my knowledge, I'm pretty sure there isn't an elegant way to do this at this time.

Here are some related ideas you can vote and comment on to add your support to encourage Microsoft to fix this limitation:

Hide/Show Column on Table

Show/Hide columns in report based on expression.

Power BI hide/show column

and here is a workaround that you may refer to:

Create a separate dim table just with measure name as below:

Then create another measure:

Measure = IF(SELECTEDVALUE('Table'[Type])="Average",[Average] ,IF(SELECTEDVALUE('Table'[Type])="Count",[Count]))

Now drag the field Type from this new table and this new measure into a visual.

and here is sample pbix file, please try it.

Best Regards,

Lin
