Phoenix tables allow you to change the text displayed on tables. One can select Options>Column Titles and enter a text string to search for (in the titles) and be replaced. The default setting is to look for that text anywhere in the column title (what is known as a partial search). In the example below if one enters to search for ‘c’ and replace with ‘Capsule’, it will do a search for any lower letter ‘c’ and do the replacement.
This could be a problem as you can see in this case the word ‘Subject’ becomes ‘SubjeCapsulet’
To prevent this to happen that search should be removed and a new one created where the box ‘Match entire cell’ is selected as depicted below and the object executed.
