[英]html/css: table/grid of input elements enclosed in parenthesis
I need a table/grid of 2x2 input elements, enclosed in parenthesis. 我需要用括号括起来的2x2输入元素的表/网格。
The objective is, in a page with a mathematics test, allow user to introduce the values of a matrix. 目的是在带有数学测试的页面中,允许用户介绍矩阵的值。 The matrix must appear in the usual form of parenthesis enclosing it.
矩阵必须以括号的通常形式出现。
That is, starting from this code or anything equivalent: 也就是说,从以下代码或任何等效代码开始:
<html> <body> A + B = <table> <tr> <td><input type="text" $INPUT_PATTERN name="a11" autofocus/></td> <td><input type="text" $INPUT_PATTERN name="a11" autofocus/></td> </tr> <tr> <td><input type="text" $INPUT_PATTERN name="a11" autofocus/></td> <td><input type="text" $INPUT_PATTERN name="a11" autofocus/></td> </tr> </table> </body> </html>
two corrections must be done: 必须进行两个更正:
Note: the page supports MathJax, thus, solutions using MathJax are also valid. 注意:该页面支持MathJax,因此,使用MathJax的解决方案也是有效的。
Here's a way to do it using the table that you already have. 这是一种使用现有表进行操作的方法。 Note that I used inline styles merely for the demo.
请注意,我仅将内联样式用于演示。 You can create a style class as needed
您可以根据需要创建样式类
<html> <body> <table> <tr> <td rowspan="2"> A+B= </td> <td rowspan="2" style="font-size:2em">(</td> <td><input type="text" $INPUT_PATTERN name="a11" autofocus/></td> <td><input type="text" $INPUT_PATTERN name="a11" autofocus/></td> <td rowspan="2"><span style="font-size:2em">)</span></td> </tr> <tr> <td><input type="text" $INPUT_PATTERN name="a11" autofocus/></td> <td><input type="text" $INPUT_PATTERN name="a11" autofocus/></td> </tr> </table> </body> </html>
