3  Elements of the Program.                              I initiate

We will see later like to realize the principal tasks in the construction of a table with our program.

• How does one work with the Alignment of the Text?
• How To insert or To erase(smear) the rows and columns of a table?
• How does one work with the Lines or Edges?
• How does one work with the colors?
• How do several cells join (multicolumn)?
• How are the broad ones of the columns modified or fix?
• How to work with the selection of cells?

How does one work with the Alignment of the Text?

• There exists a bar of buttons that facilitates the alignment of the text.
  
  

  
  

  
  On having done click with the mouse, on the first three buttons of this bar of buttons, it is allowed to us align the text of the column of the table in the one that is the selected cell, well to the left side, well centred, and well to the right, respectively.
  If simultaneously to the click of the mouse we have pressed the key CTRL, we will achieve that the corresponding alignment is applied only to the cell selected in this moment.
• In the menu of the program, we can realize the same operations, both for column and for cells.
  

  

• In the hanging menu, also there exist two options that allow us to align the text.
  

   

  In this case, the first one it(he,she) is changing consecutivly the alignment of the column the one that is the cell selected, that is to say on having pulsated F8 (a key abridged to manage to realize this option of the hanging menu) consecutivly we are going to change the alignment according to the following cycle: Left side -> Centred -> Right -> Left side...
   

How To insert or To erase(smear) the rows and columns of a table?

• The following bar of buttons facilitates the insertion to us or erased(smeared) of the rows and columns of a table
  

  

  The first and second button they allow us to insert a row, before or later respectively, of the row in the one that is the selected cell. The third and fourth button they allow us to insert a column, before or later respectively, of the column in the one that is the selected cell.
  The fifth and sixth button they allow us to erase(smear), the row or the column respectively, in that one finds the selected cell.
  
• In the menu of the program, we can realize the same operations, so much of insertion as(like) of erased(smeared).
  

  

• In the hanging menu, in the submenú INSERT and DELETE, also the same options of alignment exist and erased(smeared).
  

              

How does one work with the Lines or Edges?

• The following bar of buttons they allow us to add or to eliminate a horizontal line to the row or vertical line to the column in the one that is the selected cell, or when we keep touched the key CTRL that adds or eliminates the edge of the selected cell.
  

  

  The first button refers to the top edge, the second button to the low edge, the third button to the left edge, the fourth button to the straight edge, and the fifth button adds all the edges or eliminates all the edges of the selected cell.
• In the menu of the program, also the same possibilities exist.
  

  

• In the hanging menu, also there exist four options that allow us to add edges to the table.
  

  

  
  In this case, with F9 manage to add a vertical line to the right of the column in the one that is the selected cell or to eliminate this vertical line. With F10 manage to add a horizontal line lower than the row in the one that is the selected cell or to eliminate this horizontal line.
  With CTRL+F9 manage to add or to eliminate the straight edge of the selected cell, and with CTRL+F10 manage to add or to eliminate the low edge of the selected cell.

How does one work with the colors?

• The following bar of buttons allows us to work with the colors that we will use in the table.
  

  

  When we write the text of the cells of the table, the first button of this bar of buttons is highlighted (since(as,like) it(he,she) appears in this figure).
  
  But for colorear the bottom(fund) of the cells of the table, we will have to activate the second button. Once touched this button, the cursor will happen(pass) to have the form of a hand, and on having pulsated on a this(this one) cell will happen(pass) to have the color of bottom(fund) that appears in the bar of buttons in fourth position. To change this color, only we have to do click with the mouse on him(it) (white square, in this case), and us a picture of dialogue will appear where we will be able to select the color wished for the bottom(fund) of cell.
  

  

  
  The bar of buttons would happen(pass) to have now the following aspect:
  

  

  To give color to the text (or letters) of the table, we will have to activate the third button. Once touched this button, the cursor happens(passes) to have the form of a felt-tip pen, and on having pulsated on a this(this one) cell it(he,she) will happen(pass) to have the text with the color that appears in the bar of buttons in fifth position. To change this color, only we have to do click with the mouse on him(it) (black square, in this case), and us a picture of dialogue will appear, like the previous one, where we will be able to select the color wished for the text.
  
  The bar of buttons would happen(pass) to have now the following aspect:
  

  

  
  Also we have the possibility of colorear the bottom(fund) or the text of the whole column or of the whole row. For it we will have to puncture or in the row head-board (row 0) or in the column head-board (column 0) on one of his(her,your) cells, which would indicate that column or row would be the colored one, respectively.
  

            

  
  The sixth button allows us to copy the color of bottom(fund) of the cell selected to the color of bottom(fund) for fault, and the seventh button allows us to copy the color of text of the cell selected to the color of text for fault.

• The following bar of buttons allows us to be employed with the union / disunity of cells (multicolumn) at a table.
  

  

  
  The first button allows us to join several cells of the same row (multicolumn). On having pulsated on this button he(she) asks us how many cells we want to join from the selected cell and later it(he,she) will join them.
  With the second button we undo the union of the cells in which we are. If we touch the key CTRL simultaneously with this button, it(he,she) eliminates all the cells joined in the table.

How are the broad ones of the columns modified or fix?

• The broad ones of column can be modified by help of the mouse, on having displeased the column divider adequately, since we can estimate in this sequence of images
   
  In the first image of the sequence it(he,she) is estimated since(as,like) the form of the cursor changes on having approached the column divider. To obtain a wished fixed width, we do click with the mouse in the moment that this form adopts the cursor, and keep it  touched dragging up to obtaining the width of wished column.
  In the second image of the sequence it(he,she) appreciates the width that we have given to the second column. This operation has established a fixed width for this column, and the exits Latex will be with a type of column: p {anchofijo} (for example: p {3cm}).
  In the third image of the sequence, indicated with a red square, TABLES it(he,she) indicates with this highlighted button that it is a question of a column with fixed width.
  If we want that this column stops having a fixed width, we do click on the highlighted button.
  If this button is not highlighted and we do click on him(it), achieve that the width of the column in which we are become fixed.
• The buttons quarter(room) of the following bar of buttons
  

  
  

  We have seen that has functions in the previous paragraphs.
  The fifth button allows us to copy broad from other columns to the column of the cell in which we are.

How to work with the selection of cells?

• To work with the selection of cells we have to activate the above mentioned option in the following bar of buttons
  

  

  In the highlighted button. On having done click on him(it) a bar of buttons will appear with specific operations to be employed with the selection of cells at the left part of the application
  

  

  The first button allows us to initiate the selection (also pulsating F3 we obtain the same function) and if we return to pulsate on him(it) it(he,she) finishes the operation of selection, obtaining this way a rectangle of selected cells.
  

  

  In this example, we see since(as,like) the rectangle turns out to be selected, in that the cell (1,1) is the top left corner (the first time that we touch F3) and the cell (3,2) is the low straight corner (the second time that we touch F3).
  If we touch the second button we undo the selection of the rectangle (or we pulsate Ctrl+F3).
  With the following buttons we can realize particular operations with the selected rectangle:
  • The third button allows us to copy the content of the rectangle selected in another rectangle which dimensions are the same but his(her,your) top left corner is that of the cell in which we are (in the graphical example, it might be the cell (5,5)).
  • The fourth button allows us to copy the content of the rectangle selected in another rectangle which dimensions are those of the rectangle or counterfoil traspuesta, but his(her,your) top left corner is that of the cell in which we are (in the graphical example, it might be the cell (5,5)).
  • The fifth button allows us to erase(smear) the content of the selected rectangle.

  With one selected rectangle, the operations of

  • To complete the complete edge
  • Any of the edges touching simultaneously the key CTRL
  • Color of bottom(fund)
  • Color of letter

  They would be realized on the selected rectangle and not on the cell in which we are.
