First open Excel, all the forms are uniform width and height, which for our various data entry, I am afraid it does not look so beautiful, so we need to adjust the size of the cell width. Take the first horizontal cell, we want to make it a little taller.
Let's put the mouse pointer over the middle line between 1 and 2, allowing the mouse to turn into a cross. This turns the mouse into a state that can be dragged up and down.
Dragging this middle line down, you want to let it get a lot of distance, until you reach the desired height, release the mouse, so that an entire row of cell height to achieve the same height you need.
If you want to set a whole column of cells to the same height, use the left mouse button to select the left side of the number bar, drag down. Select the cells you want to change the format to.
Likewise, drag the middle line between the two cells with the mouse pointer and drag to the desired size, releasing the mouse. At this point, the cells you select are the same size.
Changes the width and height of the cell so that it not only facilitates the aesthetic setting of the entire document, but also facilitates the operation of related tables.
