\t is just literal t here. For tab, use "$(printf '\t')" instead.
Problematic code
# Want tab
var=foo\tbar

or
# Want linefeed
var=foo\nbar

Correct code
var="foo$(printf '\t')bar"  # As suggested in warning
var="$(printf 'foo\tbar')"  # Equivalent alternative

or
# Literal, quoted linefeed
line="foo
bar"

Rationale
ShellCheck has found a \t, \n or \r in a context where they just become regular letter t, n or r. Most likely, it was intended as a tab, linefeed or carriage return.
To generate such characters (plus other less common ones including \a, \f and octal escapes) , use printf as in the example. The exception is for linefeeds that would be stripped by command substitution; in these cases, use a literal quoted linefeed instead.
Other characters like \z generate a [[SC1001]] info message, as the intent is less certain.
Exceptions
None.
