script to show all the permissions for a table

inside my database I have a procedure called spGen2_tblIE_SchedProcess_Update.

when I run this script

select * from sys.objects
where name = 'spGen2_tblIE_SchedProcess_Update'

Inside the same database I have a table called tblIE_Step

when I run the following script

select * from sys.objects
where name = 'tblIE_Step'

then I want to see all the permissions of the objects.

when I check my stored procedure
I run this script:

select 'Proc' = SCHEMA_NAME(p.schema_id)+'.'+p.name
    , 'Type' = per.state_desc, 'Permission' = per.permission_name
    , 'Login' = pri.name, 'Type' = pri.type_desc 
    , *
From sys.objects as p
left join sys.database_permissions as per on p.object_id = per.major_id
left join sys.database_principals as pri on per.grantee_principal_id = pri.principal_id
where p.object_id = 87671360

and I get the permissions:

But when I run the same for my table, I don't get anything:

select 'Proc' = SCHEMA_NAME(p.schema_id)+'.'+p.name
    , 'Type' = per.state_desc
    , 'Permission' = per.permission_name
    , 'Login' = pri.name, 'Type' = pri.type_desc 
    , *
From sys.objects as p
left join sys.database_permissions as per on p.object_id = per.major_id
left join sys.database_principals as pri on per.grantee_principal_id = pri.principal_id
where p.object_id = 389576426

I know there are logins and groups that belong to roles that are have db_reader and db_writer permissions.
However, they are not showing here.

How can I change my script so that it would show me all the permissions for this table?

I found a good script to see the permissions on a database object.

SELECT
  (
    dp.state_desc + ' ' +
    dp.permission_name collate latin1_general_cs_as + 
    ' ON ' + '[' + s.name + ']' + '.' + '[' + o.name + ']' +
    ' TO ' + '[' + dpr.name + ']'
  ) AS GRANT_STMT
FROM sys.database_permissions AS dp
  INNER JOIN sys.objects AS o ON dp.major_id=o.object_id
  INNER JOIN sys.schemas AS s ON o.schema_id = s.schema_id
  INNER JOIN sys.database_principals AS dpr ON dp.grantee_principal_id=dpr.principal_id
WHERE 1=1
    AND o.name IN ('YOUR TABLE NAME')      -- Uncomment to filter to specific object(s)
--  AND dp.permission_name='EXECUTE'    -- Uncomment to filter to just the EXECUTEs
ORDER BY dpr.name

the script above works for a database object.
however,
when I add permissions on the schema where the db object is, the above script does not pick that up, for example:

grant delete on schema::dbo to [db_webUser] 
GO

so for that case I found this script here that caters for that as well:

SELECT
state_desc + ' ' + permission_name +
' on ['+ ss.name + '].[' + so.name + ']
to [' + sdpr.name + ']'
COLLATE LATIN1_General_CI_AS as [Permissions T-SQL]
FROM SYS.DATABASE_PERMISSIONS AS sdp
JOIN sys.objects AS so
     ON sdp.major_id = so.OBJECT_ID
JOIN SYS.SCHEMAS AS ss
     ON so.SCHEMA_ID = ss.SCHEMA_ID
JOIN SYS.DATABASE_PRINCIPALS AS sdpr
     ON sdp.grantee_principal_id = sdpr.principal_id
where 1=1
  AND so.name = 'ItemStock'

UNION

SELECT
state_desc + ' ' + permission_name +
' on Schema::['+ ss.name + ']
to [' + sdpr.name + ']'
COLLATE LATIN1_General_CI_AS as [Permissions T-SQL]
FROM SYS.DATABASE_PERMISSIONS AS sdp
JOIN SYS.SCHEMAS AS ss
     ON sdp.major_id = ss.SCHEMA_ID
     AND sdp.class_desc = 'Schema'
JOIN SYS.DATABASE_PRINCIPALS AS sdpr
     ON sdp.grantee_principal_id = sdpr.principal_id
where 1=1

order by [Permissions T-SQL]
GO

when I run the script above I get the following result, which includes the permission on the schema that reflects on my table.
