I don't have the option to create a new table in my database

Question

Hi, I have SQL 2014, for some reason, a few weeks ago I was able to create a new table for my databases, now, I don't have the option to do so, all I get when I right click on tables is "Tables..." instead of "New Table", when I select
"Tables..." it allows me to write my codes but it doesn't save except in a text files witch doesn't want to open when I want to resume my work.
Is there any option in SQL to activate the "New Table" by right clicking on Tables? I have all the rights and permissions available to my use as it's my computer and my own server. 
To fix the issue I tried
-Re-installing SQL
-Changed for 4 different versions
-Allowing more than necessary permissions 
-Making it public to use (it's only to test it, anyway, I'm in the learning phase)
Any kind of help or advice will be welcome and much appreciated.
Thank you!

I don't know the reason why you are experiencing this, so what I am describing below are just some steps that you can take to diagnose the problem if it is related to a permissions issue.
1. If you are not already on the computer where SQL Server is installed, login on that box and launch SQL Server Management Studio and run it as Administrator.
2. Connect to the Server and open up the object explorer and expand the Security node that is directly under the Sever tab.
3. Under logins, find your login, right-click properties and see what kind of server level permissions you have, and which databases you are mapped to and what kind of permissions you have on those.
It may just be that this is not related to permissions at all, but I can't think of what that would be. To test whether it is a SSMS GUI problem or not, open up a query window and select a database on which you think you have permissions to create tables.
Then create a test table using T-SQL, for example:
create table dbo.MyTestTable( col1 int);
