Compare In[1]:= TableForm[{{0.473}}, TableHeadings -> {None, {"Value"}}] TableForm[{{0.473}}, TableHeadings -> {{"Raw 1", "Raw 2"}, {"Value 1", "Value 2"}}] TableForm[{{0.473}}, TableHeadings -> {{"Raw 1"}, {"Value 1", "Value 2"}}] TableForm[{{0.473}}, TableHeadings -> {{"Raw 1"}, {"Value 1"}}] TableForm[{{0.473}}, TableHeadings -> {{}, {"Value 1"}}] TableForm[{{0.473}, {}}, TableHeadings -> {None, {"Value"}}] Note that the last line displays the header and the values correctly line but at the cost of an additional empty raw.
