How to Use rbind and cbind on Single Dataframe

Question

Sorry for framing the question incorrectly. As a beginner, I'm attempting to learn R on my own.

I have a situation where,

t1_df

id   name   address
1     x       india
2     y       usa

t2_df

id   name   address
3     a      india
4     b       usa

Now i tried to add extra column "msg" using data.frame i.e

t1_df <- data.frame(t1_df,msg)
t2_df <- data.frame(t2_df,msg)

t1_df

  id   name   address   msg
  1     x       india   hi
  2     y       usa     hello

t2_df

id   name   address   msg
3     a      india     go
4     b       usa      bye

when i tried to do rbind it gives error as col names are not matching because both df's having different col names

When i tried to cbind on both df's into single dataframe is t, it included all the columns from both df's i.e

colnames(t)

id   name   address   t1_msg   id   name   address   t2_msg

But i would like to get the dataframe as

id   name   address   t1_msg   t2_msg
  1     x       india   hi       NA
  2     y       usa     hello    NA
  3     a      india     NA      go
  4     b       usa      NA      bye

How do I obtain the output that I described above?

Help me out, please.
