ExecCommand and DHTMLEDLib.DEInsertTableParamClass

[dd]

Cannot figure it out. If somebody can help, I'd appreciate it.
I am using DHTML Edit control from C# for editing HTML pages. I am trying to
insert a table into an HTML page and I keep getting an error. Here is the
code:
DHTMLEDLib.DEInsertTableParamClass oTableParam = new
DHTMLEDLib.DEInsertTableParamClass();
oTableParam.NumCols = 3;
oTableParam.NumRows = 3;
oTableParam.TableAttrs = "align=\"left\" border=\"1\" width=\"100%\"";
ctlEdit.ExecCommand(DHTMLEDLib.DHTMLEDITCMDID.DECMD_INSERTTABLE,
DHTMLEDLib.OLECMDEXECOPT.OLECMDEXECOPT_DODEFAULT, ref oTableParam);

The problem is that this method expects ref object as a parameter where I
use oTableParam. But oTableParam is actually DEInsertTableParamClass. This
does not compile. When I used this

object oTableParam = null; //or object oTableParam = "";
It compiles but gives an exception.

Casting an object to oTableParam does not work either.

Does anyone know how to overcome this?

How about keeping oTableParam as is, but then:

object oOther = oTableParam;
ctlEdit.ExecCommand(
DHTMLEDLib.DHTMLEDITCMDID.DECMD_INSERTTABLE,
DHTMLEDLib.OLECMDEXECOPT.OLECMDEXECOPT_DODEFAULT,
ref oOther);
