Timerange filter from selected row

You can do all of those steps with a measure, which you use to filter Table 2. 

If you use:

Table Filter Measure = 
var 
    _start = SELECTEDVALUE('Table'[Start])
var 
    _end = SELECTEDVALUE('Table'[End])
var
    _date = SELECTEDVALUE('Table (2)'[Date])
return
    IF( _date <= _end && _date >= _start, 1,0)

 Then that will give you 1s for any row within the date range, when you select a row from Table

You can then apply that as a filter to a visual

Or to filter another measure, such as

Filtered Measure = CALCULATE ( [Measure], FILTER( Table2, [Table Filter Measure] = 1 ) )
