Formatting output table

Shell Programming and Scripting

I have an issue with formatting my output table. It is not correctly formatted

BEGIN{
   width=70
   qq="\""
   numSuf="^[0-9.]+[MGT%]?$"
   printf("<table border=1 width=%s%c cellspacing=0 cellpadding=0 align=left>", width, "%")
}
FNR==1{NF--}
{
   print "<tr>"
   for(i=1;i<=NF;i++)
     printf("<td style=%stext-align:%s;%s> %s </td>\n", qq, ($i~numSuf)?"right":"left", qq,$i)
   print "<tr>"
}
END {
   print "</table>"
}

and this is my output

Even after increasing my table width the first row is still messed up. Could anyone help me figure out why is it like that?

Hi,

  • What does your input look like?
  • Is that df -h output?
  • What is your OS and platform?

  • my input looks like this
Filesystem            Size  Used Avail Use% Mounted on

Hi @batmanstan

You need to use the colspan attribute to get your table to format correctly.

See:

Another thing you could check is the following df options:

'-P'
'--portability'
     Use the POSIX output format.  This is like the default format
     except for the following:

       1. The information about each file system is always printed on
          exactly one line; a mount device is never put on a line by
          itself.  This means that if the mount device name is more than
          20 characters long (e.g., for some network mounts), the
          columns are misaligned.

thanks you that works, dont mind i have another problem. It is to display my asm votedisk in a table, are there options for that also?

##  STATE    File Universal Id                File Name Disk group
--  -----    -----------------                --------- ---------
 1. ONLINE   ae971fc838f54fc1bfd426c8497afd38 (/dev/asm-disk1) [DATA]
Located 1 voting disk(s).

this should be somewhat similar to the scripting for df -h provided previously - definitely not the same, but the concepts should be the same.
I believe the output is from running crsctl query css votedisk mentioned here.
Where this command has a similar -P option as the df does, it should be in the manual (if that is your question).
Could you post a "the similar script as above", please.
What is "broken"?
P.S. just ran your awk script against your NEW sample data - it looks like it creates the html file that the browser displays exactly like you quoted above.
What's broken?

i dont think the script is broken, its just that format the output to fit the table nicely. The table includes the "--------" and "located 1 voting disk", just wondering is there a way to not include those two.

sure, just change the script to skip these 2 patterns when processing records/lines.
Give it a whirl and see how far it gets you.
