In my handson table, some columns are readOnly and some have validations (with respect to length of the input value) but when I insert a new row, the readOnly property is made false. But when I try to copy the data from the readOnly cell or the cell with validation, then it does not get copied using fillHandle. Is there any limitation of the fillHandle hook that it will not work on cells with readOnly or which have some validations on it? Please do let me know soon. Thank you.
