Can anyone help me draw this table?

Like this:

• Your problem is caused because the content in the multirow cell is higher then sum of heights of rows spanned by this cell.
• One possible work around is add vertical spaces in all cells, for example with use of the makegapedcells or with use of cellspace package and reduce linespread in table text.
• Unfortunately makegapedcells is not compatible with m column types, but this can be fix with hack suggested by Ulrike Fisher.
• Since you not provide any information about your page layout, in MWE below it has 20mm with page borders. In the case, that you have wider pages' borders, than may suggested solution in MWE below will not give satisfied result. In such a case I will need to tweak cell gapes and number of lines in in multi row cells.
