Another option is to

Create these columns in the table

col ?

was _1 per cociente(day([date]),7)

Return

if(_1 to 0.7,_1)

fila - mod(day([date]),7)+1

User row as row or matrix and Col as array column.

You can do conditional formatting using a color measure

Examples

if(FIRSTNONBLANK('Table'[Value],"true")= "true","green","red")

if(FIRSTNONBLANK(date[date],blank())= today(),"green","red")
if(max(date[date])= tofay(),"green","red")

Colour = 
SWITCH(TRUE(),
'Table'[Date] < TODAY(), "red",
'Table'[Date] = TODAY(), "orange",
"green")
