How to make table with row name and column name I am new to databases and now i came to a point where i need more complex table.
I have a table which contains site details. Each site can have multiple devices. Each device have multiple measurement tables.

Structure looks like this:

                    DEVICE LIST TABLE 1 ► MEASUREMENT TABLE (each device)
SITE LIST TABLE ►   DEVICE LIST TABLE 2 ► MEASUREMENT TABLE (each device)
                    DEVICE LIST TABLE 3 ► MEASUREMENT TABLE (each device)


Measurement table looks like this

+----+----+----+----+----+
|    | F1 | t1 | F2 | t2 |
+----+----+----+----+----+
| A1 |    |    |    |    |
+----+----+----+----+----+
| A2 |    |    |    |    |
+----+----+----+----+----+
| A3 |    |    |    |    |
+----+----+----+----+----+
| A4 |    |    |    |    |
+----+----+----+----+----+
| A5 |    |    |    |    |
+----+----+----+----+----+
| A6 |    |    |    |    |
+----+----+----+----+----+


I do not understand how to make table like this. If not possible what is the best practice to link every ROW with device.

Or should i create dynamically measrements A1 to An?

+-----------+---------+----+----+----+----+
| device_id | name    | F1 | t1 | F2 | t2 |
+-----------+---------+----+----+----+----+
|           | A1...An |    |    |    |    |
+-----------+---------+----+----+----+----+


And then do

SELECT * FROM measurement_table WHERE device_id = x
You should revise your table structure. 
You are trying to put too many different things into one table. 

What you could do is have multiple tables like so:

Table: site
Has an ID and all other details about the site! 
Table: Devices
Has an ID and all other details about the device. 
Table: measurements 
Has an ID and all other details about the measurement.

Now depending on if your measurements are linked to a single device or not you may need an intersection table or a device ID on the measurement,  and the same goes for the site. 

When you wish to select all the details about a site,  you will need to use joins to get everything,  or maybe multiple queries.
