Hi, I need lines under column headers and at the bottom of the table. The lines are displaying but not properly. Line spills onto the next line. I am using a macro variable and compute blocks to get the lines. Macro variable is %let headline = %sysfunc(repeat('_',&ls-2)). &ls is another macro variable for line size and is currently set at 133 from what I can tell. If anyone has a better way to get the lines, please let me know. I already have headline and headskip options on proc report and a paging variable called pg. I have break after pg / page.

I would like the yellow to go away. Same is happening for line under the table.

Okay, I think I fixed it by using these macro variables instead of &headline. 

  %let bb=\brdrb\brdrs\brdrw10;
  %let tb=\brdrt\brdrs\brdrw10;
