Issue
You inserted an Excel OLE sheet. However, after you modified the sheet in Microsoft® Excel by adding columns or lines, the OLE object was not updated, and the additional columns or rows were not displayed in AutoCAD®.
Solution
This behavior indicates that the OLE was not inserted as a linked object. The option to link an OLE is only available if you choose the Create from File option during object insertion. If you insert the object using the Create New option, the object will not be linked.
To insert a linked OLE object
Create the table in Microsoft® Excel and save it as an XLS file.
In AutoCAD®, click Insert menu > OLE Object.
In the Insert Object dialog box, select Create from File and then click Browse to select the file that you created in step 1.
Select the Link check box.
Click OK.
When you insert new columns or rows into the OLE, the OLE will be updated in AutoCAD after you have closed Excel.
Note: In some cases, to make the changes take effect in AutoCAD, it may be necessary to open the file in Excel again by double-clicking it and then closing it immediately.

Solution
To insert an OLE object in AutoCAD® that will update when the source document is changed, you must use the Paste Special option:
Open the source program, select and copy the entries that you want to use.
Open the destination drawing in AutoCAD or AutoCAD LT.
On the Edit menu, click Paste Special.
Select the Paste Link option, and then click OK.
The resulting OLE object will update as desired.
