I'm new to use crystal report and Asp.net, here're some problem struggle with for a long time when I design a report layout.

1.
how to use a picture as a watermark to put on the bottom layer? now my picture is under characters but above table border.

2.
In my report, there are many columns in a row, for example A,B,C columns, A column contents is around 15~1000 characters, B and C are just 1.

In my situation, if I use line or square as a table border, they're no autosize function so I have to set the maximum height, but if I use text object border then I can't let all columns's border grow in same height, and I can't find vertical align either.

please give me suggestions, I'll really appreciate :)
