Do you remember the number grids from your schools days, where you filled in the multiplication answers? What's 4 times 8? Or 9 times 7?  If you need a refresher, or you're helping someone learn them, I've got an Excel multiplication table practice workbook for you.

您还记得上学时填写乘法答案的数字网格吗？ 4乘8是多少？ 还是9乘7？ 如果您需要复习，或者正在帮助某人学习它们，我为您准备了一个Excel乘法表练习工作簿。

在家学习 (Studying at Home)

Those times tables came back to haunt me this year, when the schools closed because of the pandemic.

那些时间表在今年再次困扰着我，当时学校因为大流行而关闭。

Students were working from home, so I had Zoom meetings with my grandson, and helped  with his math homework. We did lots of work on those times tables!

学生们在家中工作，所以我和孙子开了Zoom会议，并帮助他做数学作业。 我们在那些时间表上做了很多工作！

Excel乘法工作簿 (Excel Multiplication Workbook)

The school year has ended now, but maybe my grandson wants to practise his times tables all summer! (or not)

现在学年结束了，但是也许我的孙子整个夏天都想练习他的时间表！ (或不)

Just in case, I've made an Excel multiplication table practice workbook, and you can download a copy too.

为了以防万一，我制作了一个Excel乘法表练习工作簿，您也可以下载一个副本。

There's a link near the end of this blog post, and there are a couple of videos too, with times table memorization tips.

此博客文章结尾附近有一个链接，也有一些视频，其中包含时间表存储技巧。

时间表练习–一排 (Times Table Practice – One Row)

There are 2 practice sheets in the Excel multiplication workbook.

Excel乘法工作簿中有2个练习表。

On the OneRow practice sheet, pick a number, from 1 to 12, from a drop down list.

在OneRow练习表上，从下拉列表中选择一个数字，从1到12。

Then, fill in the grid with the multiplication answers – or your best guess!

然后，用乘法答案或您的最佳猜测填写表格！

To check your answers, choose Yes from another drop down list.

要检查您的答案，请从另一个下拉列表中选择“是”。

Wrong answers are highlighted with orange fill colour. Uh oh, time to do another practice!

错误答案以橙色填充颜色突出显示。 嗯，是时候再练习一次！

时间表网格 (Times Table Grid)

On the other practice sheet, named Table, you'll choose a range of numbers that you want to practise.

在另一个名为Table的练习表上 ，您将选择一个要练习的数字范围。

Rows are created for that range of numbers, where you can fill in the multiplication answers.

将为该数字范围创建行，您可以在其中填写乘法答案。

Then, select "Yes" from the Check drop down, to highlight any errors.

然后，从“检查”下拉列表中选择“是”，以突出显示任何错误。

突出显示错误答案 (Highlight Wrong Answers)

Here's the formula for the Conditional Formatting rule, to highlight wrong answers on the Table sheet.

这是条件格式规则的公式，以突出显示表格上的错误答案。

=AND(C9<>"", $M$4="Yes", C9<>$B9*C$8)

= AND(C9 <>“”，$ M $ 4 =“是”，C9 <> $ B9 * C $ 8)

Cell E9 has orange fill because 3x3=9, and the answer was typed as 8.

单元格E9具有橙色填充，因为3x3 = 9，答案键入为8。

NOTE: Cell M4 has the drop down list, where you choose "Yes" to check your answers.

注意 ：单元格M4有一个下拉列表，您可以在其中选择“是”来检查答案。

在网格中添加单元格边框 (Add Cell Borders in Grid)

To keep the Table sheet from looking cluttered, cell borders are only shown for the selected range of numbers. That's done with conditional formatting, using this formula:

为防止表格看起来混乱，仅显示选定数字范围的单元格边框。 这是使用以下公式通过条件格式完成的：

=$B9<>""

= $ B9 <>“”

There are no grid borders in row 12, because cell B12 is empty.

第12行没有网格边框，因为单元格B12为空。

编号顺序 (Number Sequence)

In column B, the multiplier numbers are shown, based on the range that you selected. In cell B9, a formula links to cell D4, where you enter the first number in the range

在B列中，将根据您选择的范围显示乘数。 在单元格B9中，一个公式链接到单元格D4，在此您输入范围内的第一个数字

=D4

= D4

To create the sequence, this formula is entered in B10, and copied down to B20:

要创建序列，请在B10中输入以下公式，然后将其复制到B20中：

=IF(OR(B9="",$D$4>$F$4),"",IF(B9=$F$4,"",SUM(B9,1)))

= IF(OR(B9 =“”，$ D $ 4> $ F $ 4)，“”，IF(B9 = $ F $ 4，“”，SUM(B9,1)))

The result is an empty string ("") if:

如果满足以下条件，则结果为空字符串(“”)：

• the cell above has an empty string上面的单元格有一个空字符串
• the cell above has a number equal to the end number in cell F4上面的单元格的编号等于单元格F4中的结束编号
• the end number in F4 is greater than the start number in D4F4中的结束号大于D4中的开始号

Otherwise, the result is the number above, plus 1

否则，结果为上面的数字加1

In this example, the range is 2 to 6.

在此示例中，范围是2到6。

工作表保护 (Sheet Protection)

In the sample file, the OneRow and Table sheets are protected, without a password

在示例文件中，OneRow和Table工作表受到保护，没有密码

On those sheets,

在那些纸上

• data entry cells are unlocked数据输入单元被解锁
• all the other cells are locked所有其他单元都被锁定
• you can select the unlocked cells only您只能选择未锁定的单元格

That helps protect the worksheet formulas, so they aren't accidentally deleted.

这有助于保护工作表公式，因此不会意外删除它们。

To unprotect a sheet:

取消保护工作表：

• On the Excel Ribbon, click the Review tab在Excel功能区上，单击“审阅”选项卡
• In the Protect group, click Unprotect Sheet在保护组，单击取消保护工作表

获取样本文件 (Get the Sample File)

To get the Excel Multiplication Table Practice workbook, go to the sample files page on my Contextures site.

若要获取Excel乘法表练习工作簿，请转到Contextures网站上的示例文件页面 。

In the Functions section, look for FN0065 - Excel Multiplication Tables.

在“功能”部分中，查找FN0065-Excel乘法表 。

The zipped Excel file is in xlsx format, and does not contain any macros.

压缩的Excel文件为xlsx格式，不包含任何宏。

视频专家建议 (Expert Advice on Video)

If you're helping someone learn the times tables too, the tips and tricks in these two videos might help.

如果您还帮助某人学习时间表，那么这两个视频中的提示和技巧可能会有所帮助。

I was glad to see that they're still teaching the "Magic of 9s", which we learned long ago.  It's mentioned in both videos below.

我很高兴看到他们仍在教授我们很久以前学到的“ 9s魔术”。 在下面的两个视频中都有提及。
