FindCell searches cells for sText starting in row 1, column 1. It searches each cell in the first row, then searches the second row, and so on, until it finds a match or it reaches the end of the table.
You can use wildcards in your search text. For example, a cell with contents "First Quarter" will match the search text "First Q*".
If sText is not found, FindCell raises the exception E_ITEM_NOT_FOUND.
