我的 Ext.Grid.EditorGridPanel 有问题，我目前使用的是 ExtJS 2.3.0，无法更改。 :-(
问题如下:
我创建了一个窗口，它由 2 个 FormPanel 和它们之间的 EditorGridPanel 组成。 对于网格的 viewConfig，仅设置了“forceFit=true”，没有为 ColumnModel 设置样式或 View 选项。 只有每一列的对齐选项设置为“居中”。 ColumnModel 由 13 列组成，或多或少只有文本。 现在，我使用浏览器打开我正在使用的网站，然后打开窗口来测试 GUI。 当我尝试在单行中的单元格之间切换时，整个数据行向左移动， 这样第一个单元格就不再显示了。 将新行添加到网格后(通过添加按钮)， View 将重置，每列的所有单元格将再次正确显示。 列标题和 tbar 是固定的并且始终正确呈现。
问题出现在 IExplorer 8.0x，一个较旧的 Firefox 版本 (2.0x)，但网格在 Firefox 3.6x 和 Safari 5.0x 上工作正常。 如果有人遇到类似问题并已解决，或者知道可能导致该问题的原因，请随时回答。 ;-) 提前谢谢了!

最佳答案
首先，您似乎有一些 JavaScript 语法错误。我知道您只发布了一小段代码，但请尝试通过 JS Lint 运行整个代码。
对于初学者:
this.gridRecord: Ext.data.Record.create([
{name:'id', type:'int'},
{name:'start', type:'string'},
{name:'end', type:'string'},
{name:'mo', type:'boolean'},
{name:'tu', type:'boolean'},
{name:'we', type:'boolean'},
{name:'th', type:'boolean'},
{name:'fr', type:'boolean'},
{name:'sa', type:'boolean'},
{name:'su', type:'boolean'},
{name:'type', type:'string'}
]);
应该是:
this.gridRecord = Ext.data.Record.create([
虽然我不完全确定这会导致问题，但我看到您的列配置分配了宽度。即使您正在设置 viewConfig 属性“forceFit: true”，我怀疑编辑器可能会尝试使用您为每列设置的宽度。
看看这是否清除了任何东西。
