EF Core Execute SQL with parameters

The app is .Net Core 3.1, using EF Core 3 and a SQL Server on Azure

So I'm trying to create a table in my database with data from the client and I want to be safe from SQL injection.

So far I've tried with using a FormattableString which according to the doc is safe against SQL injection:

public Task CreateTableAsync(string tableName, JSchema tableSchema)
    {
        return TransactionAsync(async () =>
        {
            // Get the fields for the table creation
            var fields = await ParseJSchemaForCreationAsync(tableSchema);

            var sql = "CREATE TABLE {0} (";

            var sqlParams = new List<object>
            {
                tableName
            };

            var first = true;
            var count = 1;

            foreach (var entry in fields)
            {
                // entry.Value is from code so it's safe againt injection
                sql += first ? $"{{{count}}} {entry.Value}" : $", {{{count}}} {entry.Value}";
                first = false;

                sqlParams.Add(entry.Key);
                count++;
            }

            sql += ");";

            var safe = FormattableStringFactory.Create(sql, sqlParams.ToArray());

            // Create the table
            await _dbContext.Database.ExecuteSqlInterpolatedAsync(safe);
        });
    }

But I've an error : "incorrect syntax near '@p0'", despite it seems to generate a valid query (when getting the value of sage I got : "CREATE TABLE sqlDataSourceGrainTest (Id uniqueidentifier NOT NULL PRIMARY KEY, CreatedAt datetime2(0), UpdatedAt datetimeoffset(3), FirstName nvarchar(4000), Birthdate date, XId uniqueidentifier, Datetime datetime2(0), Timestamp timestamp, Height decimal(18, 2), HasFoodAllergy bit, Age bigint);"

I've also tried to use with SQLParameter (which I prefer):

public Task CreateTableAsync(string tableName, JSchema tableSchema)
    {
        return TransactionAsync(async () =>
        {
            // Get the fields for the table creation
            var fields = await ParseJSchemaForCreationAsync(tableSchema);

            var sql = "CREATE TABLE @tableName (";

            var sqlParams = new List<SqlParameter>()
            {
                new SqlParameter
                {
                    ParameterName = "tableName",
                    Value = tableName,
                }
            };

            var first = true;

            foreach (var entry in fields)
            {
                sql += first ? $"@{entry.Key} {entry.Value}" : $", @{entry.Key} {entry.Value}";
                first = false;

                var sqlParam = new SqlParameter
                {
                    ParameterName = $"{entry.Key}",
                    Value = entry.Key
                };

                sqlParams.Add(sqlParam);
            }

            sql += ");";

            // Create the table
            await _dbContext.Database.ExecuteSqlRawAsync(sql, sqlParams);
        });
    }

But I've have the error : "Incorrect syntax near '@tableName'."

Can someone help me to find the correct way to create the table? Is there any rules that say we can't use sql with parameters to create the table.

I've will also need to made update of the table, insert records and update records

Thanks

Edit: Based on answers from DavidG and HoneyBadger I've tried:

public Task CreateTableAsync(string tableName, JSchema tableSchema)
    {
        return TransactionAsync(async () =>
        {
            // Get the fields for the table creation
            var fields = await ParseJSchemaForCreationAsync(tableSchema);
            var sql = $"CREATE TABLE {tableName} (";
            var sqlParams = new List<SqlParameter>();
            var first = true;

            foreach (var entry in fields)
            {
                sql += first ? $"@{entry.Key} {entry.Value}" : $", @{entry.Key} {entry.Value}";
                first = false;

                var sqlParam = new SqlParameter
                {
                    ParameterName = $"{entry.Key}",
                    Value = entry.Key
                };

                sqlParams.Add(sqlParam);
            }

            sql += ");";

            // Create the table
            await _dbContext.Database.ExecuteSqlRawAsync(sql, sqlParams);
        });
    }

But now the error is "Incorrect syntax near '@id'" which is the name of the first parameter

SQL I see: CREATE TABLE tableTests ( @Id uniqueidentifier NOT NULL PRIMARY KEY, @CreatedAt datetime2(0), @UpdatedAt datetimeoffset(3), @FirstName nvarchar(4000), @Birthdate date, @XId uniqueidentifier, @Datetime datetime2(0), @Timestamp timestamp, @Height decimal(18, 2), @HasFoodAllergy bit, @Age bigint);"

Can't I use any parameters at all in the creation of a table?
