The columns are editable by default. Yes I agree this. But the text box (Editable text box) will be available only if we double click on the field. But in our requirement by default, that text box should be available for all the rows for a particular column.
I have attached two screenshots.
In one image, none of the columns will have editable text box.
In another image, one column with value 8 will have editable text box.
My requirement is, by default all those columns should have that editable text box (without double clicking on it).
