First, select the cell, regardless of your individual cell aligning or a large number of cells, as long as the box selected cells can be moved and copied. For example, to select the cell value of 71 in E8, and then move the mouse pointer over the cell border, there is a cross arrow symbol, as shown in the figure:
Second, press the left mouse button and drag to a new location, and then release the button to move. To copy a cell, press the CTRL key before releasing the mouse. As shown in the figure, hold down the CTRL key and drag the contents of the E8 cell to replicate in another cell. As shown in the figure:
Tips: In bulk copying and moving cells, the method is the same, the first box selected cell drag to move and copy. If you drag to a range of cells that already has content, a prompt for "replace the contents of the cell" appears, and clicking "Yes" replaces the contents of the original cell.
