我有一个webgrid,有一个列我想只对某些用户可见.目前我已按如下方式编码网格

if (Context.User.IsInRole(Role.Inputter) || Context.User.IsInRole(Role.Administrator))
{
    @grid.GetHtml(columns: grid.Columns(
        grid.Column(format: (item) => Html.ActionLink("Select", "Details", new { contractId = item.ContractId })),
        grid.Column(format: (item) => Html.ActionLink("Edit", "Edit", new { contractId = item.ContractId })),
        grid.Column("SignOffDate", "Sign Off Date",
            format: @<text> <span>@item.SignOffDate.ToString("d/M/yyyy")</span></text>),
        grid.Column("FullContractNumber", "Contract Number"),
        grid.Column("ContractTitle", "Title")
    ));
}
else
{ 
    @grid.GetHtml(columns: grid.Columns(
        grid.Column(format: (item) => Html.ActionLink("Select", "Details", new { contractId = item.ContractId })),
        grid.Column("SignOffDate", "Sign Off Date",
            format: @<text> <span>@item.SignOffDate.ToString("d/M/yyyy")</span></text>),
        grid.Column("FullContractNumber", "Contract Number"),
        grid.Column("ContractTitle", "Title")
    ));
}

但是肯定有更好的方法而不重复所有代码？2列输入之间的唯一区别是我想显示特定用户的编辑链接.那么这样做的最佳替代方式是什么？
