vim how to replace backslash and & -


i using vim , want replace
&\\ \hline \\ \hline can teach me how this? %s/\&\\/\\/gc didn't work. latex table.

inside search pattern, don't need escape & (\& special atom branches), \ needs doubled. in replacement part, & have escaped, \ (yes, bit complex, unfortunately). so, work:

:%s/&\\\\/\\\\/gc

if want assert following \hline, too, it's simpler end matching \ze (but still assert following part there); avoids having duplicate part should kept (or alternatively capture , re-insert in replacement):

:%s/&\ze\\\\ \\hline//gc
