I went through your code and found that you are calling your apex class in "doInit " which will surely return the record that you have saved again and again. In order to overcome this condition, you can call your apex method in a new method and assign that method to data table because if you will do this in the doInit then on whenever the page will be loaded, the action will be called. Please refer to the following code as it may be helpful in solving your query:
doinit : function(component, event, helper) { component.set('v.mycolumns', [ {label: 'Name', fieldName: 'linkName', type: 'url', typeAttributes: {label: { fieldName: 'Name' }, target: '_blank'}}, /*{label: 'Sister Account ', fieldName: 's1', type: 'url', typeAttributes: {label: { fieldName: 'Sister_Company__r.Name' }, target: '_blank'}}, {label: 'Sister Account ', fieldName: 's2', type: 'url', typeAttributes: {label: { fieldName: ' Sister_Company2__r.Name' }, target: '_blank'}}*/ {label: 'Division', fieldName: 'd1', type: 'text'}, {label: 'Sister Account', fieldName: 's1', type: 'text'}, {label: 'Sister Account', fieldName: 's2', type: 'text'}, {label: 'State', fieldName: 'State__c', type: 'text'}, {label: 'Type', fieldName: 'Type__c', type: 'text'}, {label: 'Owner', fieldName: 'Oid', type: 'text'} ]); var action = component.get('c.fetchRecords'); var recordId = component.get("v.recordId"); action.setParams({rid : recordId}); action.setCallback(this, function(response){ var state = response.getState(); if(state === "SUCCESS"){ var allValues = c.get("v.mydata"); for (var i = 0; i < allValues.length; i++) { var row = allValues[i]; row.s1 = row.Sister_Company__r.Name; } for (var i = 0; i < allValues.length; i++) { var row = allValues[i]; row.s2 = row.Sister_Company2__r.Name; } for (var i = 0; i < allValues.length; i++) { var row = allValues[i]; row.d1 = row.Sister_Company__r.RecordType.Name; } for (var i = 0; i < allValues.length; i++) { var row = allValues[i]; row.Oid = row.Owner.Name; } allValues.forEach(function(record){ record.linkName = '/'+record.Id; }); /* allValues.forEach(function(record){ record.s1 = '/'+record.Sister_Company__r.Id; }); allValues.forEach(function(record){ record.s2 = '/'+record.Sister_Company2__r.Id; }); */ console.log("allValues--->>> " + allValues); component.set('v.mydata', allValues); } else if(state === "ERROR") { var errors = response.getError(); if(errors){ if(errors[0] && errors[0].message){ console.log("Error Message: " + errors[0].message); } } else{ console.log("Unknown Error"); } } }); $A.enqueueAction(action); },Because when you are setting the data in remove method then it will set the list as per the deletion but as soon as the page is refreshed it will again bring the data from the apex. So you must get and set "mydata" list there.
I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.

is it possible that when i click on checkbox ,i have a field called false positive(False_Positive__c).its value would be true when i click on checkbox.
after that i will query only those records where this field is false .so the records is removed.
HOw to do it?
Any suggestions?
My Class is given below:-
public class FBGFamilyController {
@AuraEnabled
public static List<FBG_Family__c> fetchRecords(String rid) {
return [SELECT Id, Name, Owner.Name,Type__c, Sister_Company__r.RecordType.Name, False_Positive__c,
State__c, Division1__c, Sister_Company__r.Name, Sister_Company2__r.Name
FROM FBG_Family__c
WHERE Sister_Company__c =: rid
AND False_Positive__c = FALSE
ORDER BY Name ASC ];
}
