We could not reproduce the issue. Please tell us your Excel Add-ins version. Please also describe the steps you perform. What formula do you use and for which cells? Which actions should be performed to reproduce the issue?

I have the same issue, using Add-in to retrieve data from Zoho CRM v1 API.

Steps to reproduce:
  1. Open a new blank workbook in Excel
  2. Get data using connection (I used the Users table in Zoho CRM)
    A new Excel table 'Users' is created holding the retrieved data. It spans columns A:Q.
  3. Select cell R2
  4. Enter the formula =Users[Name]
    Column R is added to the table and filled with the users' names.
  5. On the Devart ribbon, click the 'Refresh' button
    You're asked "Are you sure you want to refresh data?"
  6. Click OK
    Query runs. Message is displayed: "An attempt to refresh a manually modified Excel table.
    The table was expected to contain 17 nonempty columns."
  7. Click OK
    Data is refreshed. Column R is now empty. Any formatting changes you applied to the table have gone.
I'm using the Add-in in Trial mode (I've purchased an activation key, but I'm not going to use it if you can't fix this issue).

When you refresh data in Devart Excel Add-ins 2.0.2, we do not recreate an Excel table, we just update data in it. This will prevent the crash of existing formulas that reference to not only a cell, but also to an Excel table column.

But when you add any value, not necessarily a formula, to the cell to the right of the table, the column on the right side is added to an Excel table. It is the Excel behavior, not the Devart Excel Add-ins one. After this, when you perform a refresh, an Excel table is recreated, since the table structure does not correspond to the select query (there are more columns than it should be). The column on the right side is deleted from the table. All other formulas that used column names become invalid.

You can use one of the following workarounds:
1. After your addition of the formula to the R2 cell, the R column is added to the Excel table and has the corresponding formatting. Press CTRL+Z at once. Formatting will disappear, but the formula will remain in the R2 cell. (but it will disappear from the other cells in the R column). You can use the Excel fill handle feature to make formula for each cell in the R column. The table structure is the same and during refresh, the table won't be recreated, and formula won't be deleted and remain valid.

2. –°reate a formula in the column located at the distance of 1 column from the table. In your case, it is the S2 cell.
