The computing task: group rows by the 1st column; insert the maximum value and the minimum value of each column in each group in order into the 2N columns horizontally.
| Z | N_1Max | N_1Min | N_2Max | N_2Min | Q_12Max | Q_12Min |
| A | 102 | 99 | 201 | -10 | 300 | -200 |
| B | 1004 | 1000 | 1200 | 1100 | 1300 | -900 |

Solution
Use SPL XLL to enter the following formula:
=spl("=f=(d=E(?)).fname().m(2:),d.groups(Z;${f.( replace( ""max(*):*Max,min(*):*Min"", ""*"", ~ )).concat@c()})",A1:D9)
Explanation
fname()function gets column names of the table. groups() function groups the rows and perform aggregations. m(:2) gets members from the 2nd to the last, and ~ represents the current members. ${} takes the string as a dynamical code to execute.
