sort custom column

Hi, xti224 

Try to create a measure like this:

isShow = 
var _selectedDate=SELECTEDVALUE(Date1[Date])
var _45=IF(SELECTEDVALUE(Table1[Date])<=_selectedDate&&SELECTEDVALUE(Table1[Date])>=_selectedDate-45,1,0)
return _45

And filter items with the measure equal to 1 in the filter pane

Result:

Please refer to the attachment below for details.

Hope this helps.
