The width of the column is taken from the length of the text in the field in the SQL database. Although you may only see a short bit of text such as Click Here - the database field will actually contain a much longer text string, due to all the HTML code to build the clickable link.
The column width is actually based on the SQL text and is why it appears so wide.
You can resize the column at any time, by dragging the boundaries. If it is preventing you seeing other information, you may want to consider putting the link field at the very end of the column list, so that it doesn't push other fields off the screen.
To save changes to a view, click the cog icon and select Save view settings.
