Dynamically Add Rows in Apex PageBlockTable

Controller:

public class Sample{
    
    Account acc = new Account();
    public List<Account> accList { get; set; }
    
    public Sample()
    {
        accList = new List<Account>();
        accList.add(acc);
    }
    
    Public void addAccount()
    {
        Account ac = new Account();
        accList.add(ac);
    }
}

Visualforce Page:

<apex:page Controller="Sample">
    <apex:form>
        <apex:pageBlock id="pbAcc">
            <apex:pageblockSection >
                <apex:pageBlockTable value="{!accList}" var="acc">
                    <apex:column headerValue="Account Name">
                        <apex:inputField value="{!acc.Name}"/>
                    </apex:column>
                    <apex:column headerValue="Account Number">

Salesforce Generic Sharing Record Using sObject

Sample Code:

//Create sharing object for the custom object Student
Schema.SObjectType stdShareType = Schema.getGlobalDescribe().get('Student__Share');
SObject stdShare = stdShareType.newSObject();
stdShare.put('ParentId', 'a0E0I00000fFSUBUA4'); //Set the ID of record being shared
stdShare.put('UserOrGroupId', UserInfo.getUserId()); //Set the ID of User or Group or Territory being granted access
stdShare.put('AccessLevel', 'Read'); //Set the Account access level
stdShare.put('RowCause', 'Student__c'); //Set the Row Cause reason
Database.SaveResult sr = Database.Insert(stdShare,false);

Salesforce Sharing Record Using Apex

For Custom Object:

//Create sharing object for the custom object Student
Student__Share studentShare  = new Student__Share();
studentShare.ParentId = recordId; //Set the ID of record being shared
studentShare.UserOrGroupId = userOrGroupId; //Set the ID of User or Group or Territory being granted access
studentShare.AccessLevel = 'Edit'; //Set the access level
Database.SaveResult sr = Database.Insert(studentShare,false);

For Standard Object:

//Create sharing object for the Standard object Account
AccountShare accshare = new AccountShare();
accshare.AccountId = accountId; //Set the Account ID of record being shared
accshare.UserOrGroupId = userOrGroupId; //Set the ID of User or Group or Territory being granted access
accshare.AccountAccessLevel = 'Edit'; //Set the Account access level
accshare.ContactAccessLevel = 'Edit'; //Set the Contact access level
accshare.OpportunityAccessLevel = 'Edit'; //Set the Opportunity access level
Database.SaveResult sr = Database.Insert(accshare,false);

Get All Objects and Its Fields in Salesforce Org

We can use Schema.getGlobalDescribe() to get all properties of sObject and its fields.

Apex Class:

public class SampleController {
    
    Public string selectedObj {get;set;}
    public String selectedField {get; set;}
    
    Public List<Selectoption> getObjList(){
        List<Schema.SObjectType> objList = Schema.getGlobalDescribe().Values();     
        List<SelectOption> objNames = new List<SelectOption>();
        objNames.add(new SelectOption('','-- Select --'));
        for(Schema.SObjectType obj : objList)
        {
            objNames.add(new SelectOption(obj.getDescribe().getName(),obj.getDescribe().getLabel()));
        }
        objNames.sort();
        return objNames;
    }
    
    public List<SelectOption> getObjectFields() {
        List<SelectOption> fieldNames = new List<SelectOption>();
        fieldNames.add(new SelectOption('','-- Select --'));
        if(!String.isBlank(selectedObj)){
            Map<String, Schema.SObjectType> schemaMap = Schema.getGlobalDescribe();
            Schema.SObjectType ObjSchema = schemaMap.get(selectedObj);
            Map<String, Schema.SObjectField> fieldMap = ObjSchema.getDescribe().fields.getMap();
            for (String fieldName: fieldMap.keySet()) 
            {  
                fieldNames.add(new SelectOption(fieldName, fieldMap.get(fieldName).getDescribe().getLabel()));
            }
        }
        return fieldNames;
    }      
}
