在 MATLAB Online 中打开

UC-SR 58-28 300 S3.csv

If your header is always the same size you can simply hard code which lines are header lines (in this case 19)

datatable = readtable('UC-SR 58-28 300 S3.csv','NumHeaderLines',19);

Warning: Column headers from the file were modified to make them valid MATLAB identifiers before creating variable names for the table. The original column headers are saved in the VariableDescriptions property.
Set 'VariableNamingRule' to 'preserve' to use the original column headers as table variable names.

plot(datatable.Time_s_,datatable.AxialForce,'-.')
