Answer 1

declare #x int = 4, #n int = 10
declare #strg nvarchar(1000) = 'create table myTable ('
declare #i int = 1
while #i<= #x
begin
set #strg = #strg + 'att' + cast(#i as varchar(5))+ ' int default ' + CAST(#i as varchar(5)) + ','
set #i = #i + 1
end
set #strg = SUBSTRING(#strg, 1, LEN(#strg)-1) + ')'
-- this creates your table
exec sp_executesql #strg
-- now lets insert rows
set #i = 0
while #i < #n
begin
INSERT INTO myTable DEFAULT VALUES;
set #i = #i + 1
end
-- lets check
select *
from myTable

Here's a script. You could put this into a stored procedure or just leave it as it is. All you have to do is update the initial col and row values.
DECLARE
#cols INT = 4,
#rows INT = 10,
#tablename VARCHAR(20) = 'TestTable'
DECLARE
#i INT = 1,
#j INT = 1,
#sql NVARCHAR(MAX) = 'create table ' + #tablename + '('
WHILE(#i <= #cols)
BEGIN
SET #sql = #sql + 'att' + CAST(#i AS VARCHAR(10)) + ' VARCHAR(10)'
IF NOT #i = #cols
BEGIN
SET #sql = #sql + ', '
END
SET #i = #i + 1
END
SET #sql = #sql + ')'
EXECUTE sp_executesql #sql
SET #sql = 'INSERT INTO ' + #tablename + ' VALUES'
WHILE(#j <= #rows)
BEGIN
SET #i = 1
SET #sql = #sql + '('
WHILE(#i <= #cols)
BEGIN
SET #sql = #sql + '''' + CAST(#i AS VARCHAR(10)) + ''''
IF NOT #i = #cols
BEGIN
SET #sql = #sql + ', '
END
SET #i = #i + 1
END
IF NOT #j = #rows
BEGIN
SET #sql = #sql + '), '
END
SET #j = #j + 1
END
SET #sql = #sql + ')'
EXECUTE sp_executesql #sql
Hope this helps.
