The QueryBuilder has options to sort the column fields by ascending or descending order. To sort the columns, you need to set SortDirection property.

@using Syncfusion.Blazor.QueryBuilder

<SfQueryBuilder DataSource="@EmployeeData" SortDirection="SortDirection.Ascending">
    <QueryBuilderRule Condition="or" Rules="@Rules"></QueryBuilderRule>
    <QueryBuilderColumns>
        <QueryBuilderColumn Field="EmployeeID" Label="Employee ID" Type="ColumnType.Number"></QueryBuilderColumn>
        <QueryBuilderColumn Field="FirstName" Label="First Name" Type="ColumnType.String"></QueryBuilderColumn>
        <QueryBuilderColumn Field="TitleOfCourtesy" Label="Title of Courtesy" Type="ColumnType.Boolean" Values="Values"></QueryBuilderColumn>
        <QueryBuilderColumn Field="Title" Label="Title" Type="ColumnType.String"></QueryBuilderColumn>
        <QueryBuilderColumn Field="HireDate" Label="Hire Date" Type="ColumnType.Date"></QueryBuilderColumn>
        <QueryBuilderColumn Field="Country" Label="Country" Type="ColumnType.String"></QueryBuilderColumn>
        <QueryBuilderColumn Field="City" Label="City" Type="ColumnType.String"></QueryBuilderColumn>
    </QueryBuilderColumns>
</SfQueryBuilder>

@code {
    private string[] Values = new string[] { "Mr.", "Mrs." };
    List<RuleModel> Rules = new List<RuleModel>()
    {
            new RuleModel { Field="Country", Label="Country", Type="String", Operator="equal", Value = "England" },
            new RuleModel { Field="EmployeeID", Label="EmployeeID",  Type="Number", Operator="notequal", Value = 1001 }
    };

    public List<EmployeeDetails> EmployeeData = new List<EmployeeDetails>
    {
        new EmployeeDetails{ FirstName = "Martin", EmployeeID = 1001, Country = "England", City = "Manchester", HireDate = new DateTime(2014, 4, 23) },
        new EmployeeDetails{ FirstName = "Benjamin", EmployeeID = 1002, Country = "England", City = "Birmingham", HireDate = new DateTime(2014, 6, 19) },
        new EmployeeDetails{ FirstName = "Stuart", EmployeeID = 1003, Country = "England", City = "London", HireDate = new DateTime(2014, 7, 4) },
        new EmployeeDetails{ FirstName = "Ben", EmployeeID = 1004, Country = "USA", City = "California", HireDate = new DateTime(2014, 8, 15) },
        new EmployeeDetails{ FirstName = "Joseph", EmployeeID = 1005, Country = "Spain", City = "Madrid", HireDate = new DateTime(2014, 8, 29) }
    };

    public class EmployeeDetails

        public int EmployeeID { get; set; }
        public string Country { get; set; }
