Alignment setting on individual row

<m:math display="block"> <m:mtable frame="solid" columnlines="solid" rowlines="solid" rowalign="top" columnalign="right"> <m:mtr> <m:mtd> <m:mi>xyx</m:mi> </m:mtd> <m:mtd> <m:mi>y</m:mi> </m:mtd> <m:mtd> <m:mi>z</m:mi> </m:mtd> </m:mtr> <m:mtr rowalign="bottom" columnalign="left"> <m:mtd> <m:mn>12</m:mn> </m:mtd> <m:mtd> <m:mn>2</m:mn> </m:mtd> <m:mtd> <m:mn>3111</m:mn> </m:mtd> </m:mtr> </m:mtable> </m:math>

Save the file after editing as “test.xml”. The display looks like :

xyx y z 12 2 3111

There appears serious gap in the specification for this element and implementation of the same by the browsers. For this reason, the "mlabeledtr" element is not described. Also related "side" and "minlabelspacing" of "mtable" elements are skipped. Instead, an example with equivalent effect for creating a labeled display is included in the next section titled “Application”.

The implementation of alignment within a cell is also not implemented by browsers at present. As such, "maligngroup" and "malignmark" elements along with associated "groupalign" attribute of "mtable" element are not considered.

Applications

Highlighting rows and columns with dashed line

Control on each column and row is not limited to alignment. The flexibility at the lowest level of creating table is extended to lines bordering table cells as well.

We can highlight a portion of table by assigning a particular row and column with “dashed” lines. This effect can be achieved by specifying individual row and column lines to be “dashed” as against “solid” or “none”. In the table here first row and column lines are set to none, while second row and column lines are set to “dashed”.

Highlighting rows and columns

<m:math display="block"> <m:mtable frame="solid" rowlines="none dashed" columnlines="solid dashed"> <m:mtr> <m:mtd> <m:mi>x</m:mi> </m:mtd> <m:mtd> <m:mi>y</m:mi> </m:mtd> <m:mtd> <m:mi>z</m:mi> </m:mtd> </m:mtr> <m:mtr> <m:mtd> <m:mn>a</m:mn> </m:mtd> <m:mtd> <m:mn>b</m:mn> </m:mtd> <m:mtd> <m:mn>c</m:mn> </m:mtd> </m:mtr> <m:mtr> <m:mtd> <m:mn>1</m:mn> </m:mtd> <m:mtd> <m:mn>2</m:mn> </m:mtd> <m:mtd> <m:mn>3</m:mn> </m:mtd> </m:mtr> </m:mtable> </m:math>

Save the file after editing as “test.xml”. The display looks like :

x y z a b c 1 2 3

Rows of equations

New rows in table can be introduced with “mtr” row element. This behavior is handy in displaying rows of mathematical expressions, using bare table as shown in the example :

Rows of equations

<m:math display="block"> <m:mtable> <m:mtr> <m:mtd> <m:mi>3x + y </m:mi> </m:mtd> <m:mtd> <m:mo>=</m:mo> </m:mtd> <m:mtd> <m:mn>6</m:mn> </m:mtd> </m:mtr> <m:mtr> <m:mtd> <m:mn>2x – y </m:mn> </m:mtd> <m:mtd> <m:mo>=</m:mo> </m:mtd> <m:mtd> <m:mn>4</m:mn> </m:mtd> </m:mtr> </m:mtable> </m:math>

Save the file after editing as “test.xml”. The display looks like :

3x + y = 6 2x – y = 4

Labelled equation

The label row is convenient to write numbered equation as shown here. This special row is implemented with "mlabelmtr" element.

Labelled row : equation number

<m:math display="block"> <m:mtable> <m:mlabeledtr> <m:mtd> <m:mrow> <m:mi>E</m:mi> <m:mo>=</m:mo> <m:mrow> <m:mi>m</m:mi> <m:msup> <m:mi>c</m:mi> <m:mn>2</m:mn> </m:msup> </m:mrow> </m:mrow> </m:mtd> <m:mtd> <m:mtext> (1.1) </m:mtext> </m:mtd> </m:mlabeledtr> </m:mtable> </m:math>

Save the file after editing as “test.xml”. The display looks like :

E = m c 2 (1.1)

Matrix

Use of parentheses and table without frame can conveniently be used to represent matrix as illustrated in the example here.

Matrix

<m:math display="block"> <m:mo> ( </m:mo> <m:mtable> <m:mtr> <m:mtd> <m:mi>x</m:mi> </m:mtd> <m:mtd> <m:mi>y</m:mi> </m:mtd> <m:mtd> <m:mi>z</m:mi> </m:mtd> </m:mtr> <m:mtr> <m:mtd> <m:mn>1</m:mn> </m:mtd> <m:mtd> <m:mn>2</m:mn> </m:mtd> <m:mtd> <m:mn>3</m:mn> </m:mtd> </m:mtr> </m:mtable> <m:mo> ) </m:mo> </m:math>

Save the file after editing as “test.xml”. The display looks like :

( x y z 1 2 3 )

Questions & Answers

A golfer on a fairway is 70 m away from the green, which sits below the level of the fairway by 20 m. If the golfer hits the ball at an angle of 40° with an initial speed of 20 m/s, how close to the green does she come?

chemistry could also be understood like the sexual attraction/repulsion of the male and female elements. the reaction varies depending on the energy differences of each given gender. + masculine -female.

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing
