Scispot Labsheets support adjusting the width and arrangement of columns.
To adjust the width of a column, click on the rightmost edge of the desired column in the column header. Adjust the width of the column by dragging the edge right or left; dragging left will shrink the column, and dragging right will widen it.
Double-clicking the edge will set the width to a fixed, predetermined size.
To rearrange a column, click the column header and drag it to the desired position. Preceding columns are shifted to accommodate the change.
Note that rearranging the columns changes the references of moved columns. Therefore, cells that use formulas with absolute references will change if the referenced cell has been moved.
