The code below successfully binds the data in the ListObject listTbl to the
data in the DataTable twsTable. However, it does not bind the column names
or the formatting of twsTable to listTbl. In other words, the column names
on listTbl show up on the Excel spreadsheet as "Column 1", "Column 2", etc.,
and the formatting/column widths is the default for the Excel spreadsheet.
How do I get the column names and formatting from the DataTable bound to the
ListObject?

Dim listTbl As Microsoft.Office.Tools.Excel.ListObject
Dim twsTable As DataTable

'fill twsTable with data and schema from database on SQL Server
fromtwsTable.CommandText = "SELECT * FROM [TWS IntraDay] ORDER BY Ticker"
twsTableDa.Fill(CosDB_ds, "TWS IntraDay")
twsTable = CosDB_ds.Tables("TWS IntraDay")
twsTableDa.FillSchema(twsTable, SchemaType.Source)

'add a ListTable to Excel
listTbl = Globals.Sheet1.Controls.AddListObject(Globals.Shee t1.Range("A2"),
"StockTable")

'bind the list table to the DataTable twsTable
listTbl.DataSource = twsTable


Incidentally, I tried the following:

Dim listTblCols As Excel.ListColumns = listTbl.ListColumns
For c = 0 To twsTable.Columns.Count - 1
listTblCols(c).Name = twsTable.Columns(c).ColumnName
Next c

This returns a "Bad index" COM error when I try to assign or read a .Name
value from listTblCols. When I add listTblCols to the Watch window, it shows
it's m_ObjectToDataMap as null and says "Children could not be evaluated".
However, listTblCols.Count correctly returns 11 for the column count.

Hello Ed White,

We encounter the "Bad index" COM error because the base index of the
DataTable does not match the base index of the ListObject. The dot Net
collection object always takes 0 as its base index while the office
collection object uses 1. So, we just need to make a little modification,
changing the listTblCols(c) to listTblCols(c+1) in your codes. I have
tested with the following version which works fine.

Dim listTblCols As Excel.ListColumns = listTbl.ListColumns
For c = 0 To twsTable.Columns.Count - 1
listTblCols(c+1).Name = twsTable.Columns(c).ColumnName
Next c

Please have a try and let me know if it works for you. Have a good day!

Another problem, based upon the same code above: The DataBodyRange of the
ListObject listTbl does not work. It appears to be returning DBNull.
Shouldn't this return the Range of the ListObject?

Hello Ed,

Based on my test, the listTbl.DataBodyRange will return the range of data.
The following are two scenarios,

*Before we execute the line "listTbl.DataSource = twsTable", the
listTbl.DataBodyRange will return Nothing in my side. I think this may be
what you have observed.

*After we execute the line "listTbl.DataSource = twsTable", the
listTbl.DataBodyRange will return an Excel range which represents the data
rect. In my side, the listTbl.DataBodyRange.Address is "$A$3:$B$6".

Is this what you see in your side? Have a nice day!

Interesting...when I add listTbl.DataBodyRange to the Watch window, and click
the + sign to the left of it, the only thing that comes up is
m_ObjectToDataMap with a value of Null. However, if I add
listTbl.DataBodyRange.Address, it does return the address. Normally, when
you add something to the Watch window, you can observe all of its properties
by clicking the + sign, but it's not working that way with this, and that is
why I thought is wasn't working.

Incidentally, I get the same results with listTbl.HeaderRowRange.
