In Excel, users often have to deal with cells, rows, and columns. But have you ever noticed the boundaries of Excel cells? Do you take advantage of the additional functionality that Excel provides on these boundaries? Here we first take the "column" surgery.

The difference between two functions is that Insertpoint has to complete the range check and memory allocation of the point first, and the index is slower. Note: The essence of these two functions is to invoke settuple (const vt

What to do if the cell contents are too long to be fully displayed. It would be nice if the mouse moved to the cell to automatically display all the text content.

Uitableview is a control with high usage during iOS development. For me, almost every view I make has its own figure. But for a long time, I had a superficial understanding of her. Two things that touched me a lot. One is the custom uitableviewcell mentioned above, and the other is the reuse that we will mention today.The so-called reuse of the surface meaning to understand is reuse. The general working principle is: uitableview is lazy loading, that is, loading only the part that will be displa

Recently, company projects often have this interface: A tableview, and each cell has a data, just like the interface when many user information needs to be filled in for website registration users. However, these cells are not the same. They can be set labels and cannot be edited. They can be the textfield to be input, the button pop-up window, or uiswitch.
