To create a table, you can follow this formula:

CREATE TABLE Country(Column1, Column2, Column3)

or:

CREATE TABLE Country(
Column1,
Column2,
Column3);

Each column is created as:

ColumnName DataType Options

Here is an example:

CREATE TABLE Customers (
 DrvLicNbr nvarchar(32), 
 DateIssued DATE,
 DateExpired date,
 FullName nvarchar(50),
 Address NVARCHAR(120),
 City NvarChar(40),
 State NVarChar(50),
 PostalCode nvarchar(20),
 HomePhone nvarchar(20),
 OrganDonor BIT);
GO

To start from a sample code, open an empty Query window and display the Template Explorer. From the Template Explorer, expand Table. Drag Create Table and drop it in the Query window:
-- =========================================
-- Create table template
-- =========================================
USE <database, sysname, AdventureWorks>
GO

IF OBJECT_ID('<schema_name, sysname, dbo>.<table_name, 
    sysname, sample_table>', 'U') 
 IS NOT NULL
  DROP TABLE <schema_name, sysname, dbo>.<table_name, sysname, sample_table>
GO

CREATE TABLE <schema_name, sysname, dbo>.<table_name, sysname, sample_table>
(
    <columns_in_primary_key, , c1> <column1_datatype, , int> 
 <column1_nullability,, NOT NULL>, 
    <column2_name, sysname, c2> <column2_datatype, , char(10)> 
 <column2_nullability,, NULL>, 
    <column3_name, sysname, c3> <column3_datatype, , datetime> 
 <column3_nullability,, NULL>, 
    CONSTRAINT <contraint_name, sysname, PK_sample_table> 
 PRIMARY KEY (<columns_in_primary_key, , c1>)
)
GO
You can then modify/customize this code.
To visually create a table, in the Object Explorer, expand the the database and expand its Tables node. Right-click the Tables node and click New Table... Enter a name for each column and select its data type:
