The values of Map id getting null after I perform Insert operation on the key set.

I am trying to insert the a Map of <Case,List<Case> as parents and their related child cases using apex. But once I insert the Map key set , the map values get null.

Map<Case,List<Case>> parentChildMap = new Map<Case,List<Case>>();
 List<Case> parentCases = new List<Case>();
        for(CaseWrapper wrap: caseWrapperList){
            parentChildMap.put(wrap.parentCase,wrap.childCases);
        }
        System.debug('map before insert==>'+parentChildMap);
        if(parentChildMap.keySet() !=null){
           parentCases.addAll(parentChildMap.keySet());
           insert parentCases ; 
           System.debug('map after insert==>'+parentChildMap);
        }


Debugs:
map before insert==> {Case:{Subject=1}=(Case:{Subject=1.1}), Case:{Subject=2}=(Case:{Subject=2.2})}

map after insert==> {Case:{Subject=1, Id=5000K00002cxQsWQAU}=null, Case:{Subject=2, Id=5000K00002cxQsXQAU}=null}

Why the values are geting set to null?

create a datatable inside the last column of another datatable

I have the below data containing list of roomtypes.Each room type can have multiple rates and I want to show it in a data table but I am only able to show the roomtypes values.

The table should have three colums ie. Room Type, Availability, Rate
Under the Rate column i want to create another datatable that can show Rate type, Availability,Price.

The no. of rates available for a particular roomtype is not static.Hence I need to create a dynamic table. The table should look like this.

LWC template:
       
 <div style="height: 125px;">
                <lightning-datatable
                        key-field="id"
                        data={roomTypeList}
                        show-row-number-column
                        row-number-offset={rowOffset}
                        hide-checkbox-column
                        columns={columnList}>
                </lightning-datatable>
            </div>

.js file:

const columnList = [
    {label: 'Room Type', fieldName: 'title'},
    {label: 'Availability', fieldName: 'availableroom'},
    {label: 'Rates', fieldName: 'rates'}
];

searchroom({hotelid:this.hotelid,cindate:this.checkindate,coutdate:this.checkoutdate})
            .then(result =>{
                console.log(result);
                console.log('============result '+JSON.stringify(result));
                this.roomTypeList = result;
            })

result value::::::
