具有Html.EditorFor

Question

我正在尝试使用表格创建表单。我总共有7个领域。我希望完成的是一行上有3个字段，第二行上有3个字段，最后一行是扩展的最后一个字段。我尝试使用colspan，但是NextAction的editorfor框并未一直扩展。该字段的右侧有一个空白。我尝试创建CSS类以消除空白，但是效果不佳。

如何获取它，以便NextAction字段一直扩展到最后一列？

下面，我为表的最后两行添加了代码。

            <table>
            <tr>
                <td>
                    @Html.LabelFor(model => model.Customer, htmlAttributes: new { @class = "control-label labelpadding" })
                </td>
                <td style="width:300px">
                    @Html.EditorFor(model => model.Customer, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => model.Customer, "", new { @class = "text-danger" })
                </td>
                <td>
                    @Html.LabelFor(model => model.Principal, htmlAttributes: new { @class = "control-label col-md-2" })
                </td>
                <td style="width:300px">
                    @Html.EditorFor(model => model.Principal, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => model.Principal, "", new { @class = "text-danger" })
                </td>

                <td>
                    @Html.LabelFor(model => model.Product, htmlAttributes: new { @class = "control-label labelpadding" })
                </td>
                <td>
                    @Html.EditorFor(model => model.Product, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => model.Product, "", new { @class = "text-danger" })
                </td>

            </tr>
            <tr>

                <td>
                    @Html.LabelFor(model => model.Status, htmlAttributes: new { @class = "control-label labelpadding" })
                </td>
                <td>
                    @Html.DropDownListFor(m => m.Status, new SelectList(ViewBag.Status, "Status", "Text"), new { @class = "form-control" })
                    @Html.ValidationMessageFor(model => model.Status, "", new { @class = "text-danger" })
                </td>
                <td>
                    @Html.LabelFor(model => model.Value, htmlAttributes: new { @class = "control-label labelpadding" })
                </td>
                <td>
                    @Html.EditorFor(model => model.Value, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => model.Value, "", new { @class = "text-danger" })
                </td>
                <td>
                    @Html.LabelFor(model => model.FollowUpDate, htmlAttributes: new { @class = "control-label labelpadding" })
                </td>
                <td>
                    <div>
                        <div class="input-group date" data-provide="datepicker">
                            @Html.EditorFor(model => model.FollowUpDate, new { htmlAttributes = new { @class = "form-control" } })
                            <div class="input-group-addon">

                <td colspan="5">

            </tr>
        </table>

由于在项目上启用了Bootstrap，因此请使用Bootstrap的CSS类w-100。此类将使它应用的元素具有100％的宽度。这是添加了该类的更新后的EditorFor行：

@Html.EditorFor(model => model.NextAction, new { htmlAttributes = new { @class = "form-control w-100"} })

如果这不起作用，则可能还有其他方法可以覆盖它。检查其他样式表以及浏览器中呈现的HTML。
