Failed to run Command "Columns"

[MC Hammer]

Hi everyone
I have been migrating some topics from a Flare project to another.
We have topics with large tables and we are simplifying these tables in the new project.
These tables are expandable using a form with checkboxes and some Javascript. The column headers are always the same for every topic.
I can remove all columns I need to (In the Flare editor, select column, right-hand click and select Delete | Columns) except one for which I get the following error message:

Columns.gif

What does this mean and is there a way to 1/prevent this error message from being displayed and 2/be able to actually delete this column? (After removing the columns, I will need to edit the code so the Javascript still work but I know how to do this. In the meantime, I will investigate amending the code BEFORE deleting the column for which I have the issue).
Thanks in advance for any input and suggestions.

Make sure the XML editor is in Layout (Web) to remove page breaks while deleting columns.
Just an idea.

Do you have a row with an extra "dead" cell outside the table?

I sometimes had this message when importing tables from Robohelp, where Flare didn't recognise where I'd merged cells in RH.

Had to edit the HTML to fix it.

OR just add a new, properly formatted row in Flare, copy the content and delete the offending row.

Hi there
Thanks to both for your hints. In my case, the message got displayed because I was specifying columns (<col>) that I am hiding or showing. If I remove all the <col> tags, I do not get the error message anymore and can delete the column I want. Nearly there but it is tedious...
