Is it possible to decide which line is variable names in readtable?

I want to use readtable to read data from an excel file. As I understand, in readtable, the first line is automatically the variable names. However, in my excel file, not just the first line, but the starting 3 lines contain characters and I want to know whether it is possible to use readtable to have an output where the vaiable names are the words that appear in the 3rd (or any desired) line.
A part of the excel file looks like this:
and I want the output to be like this:
ML125 MLCorr ML100 Ds
32.2 32.2 48.44 15.2

Yes, you can do that. For example,
variable_row = 3;
datatable = readtable(filename, 'VariableNamesRange', variable_row);
In some cases you want to specify a location to read the data from. You can use 'Range' in some cases, but if you have complicated headers then it might be better to use the 'DataRange' option.
Note: 'VariableNamesRange' and 'DataRange' may be specific to spreadsheets; the option names might be different for text files.
