readtable disfigures the CSV file header

I need to remove the units within brackets from my CSV file, attached.

ID	par1 (mol)	par2 (meter^3)	par3 (kg/L)
1	4	5	11
2	3	6	10
3	2	7	9
4	1	8	8

here the basic code I tried

data = readtable('headerFile.csv','ReadVariableNames', true);
headerRow = data.Properties.VariableNames

readtable however messes up the header (raplaces special characters with '_') and instead of

    {'ID'}    {'par_1 (mol)'}    {'par_2 (meter^3)'}    {'par_3 (kg/L)'}

I get

headerRow =
1×4 cell array
Columns 1 through 4
{'ID'}    {'par_1_mol_'}    {'par_2_meter_3_'}    {'par_3_kg_L_'}

What is the best way to extract the actual header?

data = readtable('headerFile.csv','ReadVariableNames', true, 'VariableNamingRule','preserve')

data = 4×4 table
    ID    par_1 (mol)    par_2 (meter^3)    par_3 (kg/L)
    __    ___________    _______________    ____________

    1          4                5                11     
    2          3                6                10     
    3          2                7                 9     
    4          1                8                 8

hello

here you are :

headerRow = {'ID'} {'par_1 (mol)'} {'par_2 (meter^3)'} {'par_3 (kg/L)'}

data = readtable('headerFile.csv','ReadVariableNames', true,'VariableNamingRule' , 'preserve');
headerRow = data.Properties.VariableNames
