question

It looks like it is, but there is a word wrap going on because the width of the column is not enough to fit the entire label. The "t" in "Count" and the last ")" in "($)" seem to be abutted against the right margin of the column

the first column has enough space but space coming after the word "Transaction" making imperfect right align, is there any solution for this to fix?

If you're saying that only the "Transaction " and "Transaction Amount " are the column headers, not including the "Count" or "($)" parts, then the answer would be to modify the column header label and remove the space.
