Answer 1

This works for the sample you have provided.

Find what: (\w*\|\w*\|\w*\|\w*)([\|\s]*)([\w\|]*)
Replace with: \1 \3

Search mode: Regular expression

Answer 2

• Ctrl+H
• Find what: ^(?:[^|]+\|){3}.*?\K\h*\|\h*
• Replace with: <-- a space
• CHECK Wrap around
• CHECK Regular expression
• UNCHECK . matches newline
• Replace all

Explanation:

^               # beginning of line
  (?:           # start non capture group
    [^|]+       # 1 or more non pipe
    \|          # a pipe, have to be escaped as it's special character for regex
  ){3}          # end group, must appear 3 times
  .*?           # 0 or more any character but new line, not greeedy
  \K            # forget all we have seen until this position
  \h*           # 0 or more horizontal spaces
  \|            # a pipe, have to be escaped as it's special character for regex
  \h*           # 0 or more horizontal spaces
