JqGrid implements this select-different options for different rows in the same column

Introduction to jqGrid

Jqgrid is a jquery-based web-side table/tree grid component.
 

 

Default select definition method

[Javascript]
{Name: 'ship ', index: 'ship', width: 90, editable: true, edittype: "select", editoptions: {value: "FE: FedEx; IN: inTime; TN: TNT; AR: ARAMEX "}}

{Name: 'ship ', index: 'ship', width: 90, editable: true, edittype: "select", editoptions: {value: "FE: FedEx; IN: inTime; TN: TNT; AR: ARAMEX "} the default definition method is to set the colModel col definition in the grid definition options according to the above definition method.
FE: FedEx => the colon is preceded by value and followed by text.

After this setting, the options of all the drop-down lists under the same column are the same. How do I set different options for this field of each row?
Datatype is not local. If it is local, the implementation is as follows:

 

Customized implementation
ColModel Definition

[Javascript]
{Name: 'note', index: 'note', editable: true, edittype: 'custom', editoptions: {custom_element: myelem, custom_value: myvalue}, width: 150, sortable: false}]

{Name: 'note', index: 'note', editable: true, edittype: 'custom', editoptions: {custom_element: myelem, custom_value: myvalue}, width: 150, sortable: false}]
Javascript function definition
[Javascript]
Function myelem (value, options ){
Var el = document. createElement ("select ");
If (value! = Null & value. length> 0)
{
Var optvalues = eval (value );
If (optvalues. length> 0)
{
For (var I = 0; I <optvalues. length; I ++)
{
Var optvalue = optvalues [I]. optvalue;
Var optdisplay = optvalues [I]. optdisplay;
Var optel = document. createElement ("option ");
Optel. innerHTML = optdisplay;
Optel. value = optvalue;
El. appendChild (optel );
}
}
}
Return el;
}
 
Function myvalue (elem, operation, value ){
If (operation = 'get '){
Return $ (elem). val ();
} Else if (operation === 'set '){
$ (Elem). val (value );
}
}

Function myelem (value, options ){
Var el = document. createElement ("select ");
If (value! = Null & value. length> 0)
{
Var optvalues = eval (value );
If (optvalues. length> 0)
{
For (var I = 0; I <optvalues. length; I ++)
{
Var optvalue = optvalues [I]. optvalue;
Var optdisplay = optvalues [I]. optdisplay;
Var optel = document. createElement ("option ");
Optel. innerHTML = optdisplay;
Optel. value = optvalue;
El. appendChild (optel );
}
}
}
Return el;
}

Function myvalue (elem, operation, value ){
If (operation = 'get '){
Return $ (elem). val ();
} Else if (operation === 'set '){
$ (Elem). val (value );
}
}

When adding data, the value of this field is assigned in json format:
[Html]
{Optvalue: 'value', optdisplay: 'display '}

{Optvalue: 'value', optdisplay: 'display '}
