Field Detail

{Object} color
color.cell defines background color for marked table cell. If not set then background color will not be changed. 
// set "#9BB3DA" as color for marked cell
REDIPS.table.color.cell = '#9BB3DA';
Default Value:
null

{Boolean} mark_nonempty
Enable / disable marking not empty table cells. 
// allow marking only empty cells
REDIPS.table.mark_nonempty = false;
Default Value:
true
Method Detail

cell_ignore(c)
Method removes attached onmousedown event listener. Sometimes is needed to manually ignore some cells in table after row/column were dynamically added.
Parameters:
{HTMLElement|String} c
Cell id or cell reference of table that should be ignored (onmousedown event listener will be removed).

cell_index(flag)
Method displays cellIndex for each cell in tables. It is useful in debuging process.
Parameters:
{Boolean} flag
If set to true then cell content will be replaced with cell index.

column(table, mode, index)
Method adds / deletes table column. Last column will be assumed if index is omitted.
Parameters:
{HTMLElement|String} table
Table id or table reference.
{String} mode
Insert/delete table column
{Integer} index Optional
Index where column will be inserted or deleted. Last column will be assumed if index is not defined.

mark(flag, el, row, col)
Method sets or removes mark from table cell. It can be called on several ways: with direct cell address (cell reference or cell id) or with cell coordinates (row and column). 
// set mark to the cell with "mycell" reference
REDIPS.table.mark(true, mycell);
 
// remove mark from the cell with id "a1"
REDIPS.table.mark(false, "a1");
 
// set mark to the cell with coordinates (1,2) on table with reference "mytable"   
REDIPS.table.mark(true, mytable, 1, 2);
 
// remove mark from the cell with coordinates (4,5) on table with id "t3"
REDIPS.table.mark(false, "t3", 4, 5);
Parameters:
{Boolean} flag
If set to true then TD will be marked, otherwise table cell will be cleaned.
{HTMLElement|String} el
Cell reference or id of table cell. Or it can be table reference or id of the table.
{Integer} row Optional
Row of the cell.
{Integer} col Optional
Column of the cell.

merge(mode, clear, table)
Method merges marked table cells horizontally or vertically.
Parameters:
{String} mode
Merge type: h – horizontally, v – vertically. Default is “h”.
{Boolean} clear Optional
true – cells will be clean (without mark) after merging, false – cells will remain marked after merging. Default is “true”.
{HTMLElement|String} table Optional
Table id or table reference.

onmousedown(el, flag, type)
Method attaches or removes onmousedown event listener on TD elements depending on second parameter value (default is true). If third parameter is set to “classname” then tables will be selected by class name (named in first parameter). All found tables will be saved in internal array. Sending reference in this case will not be needed when calling merge or split method. Table cells marked with class name “ignore” will not have attached onmousedown event listener (in short, these table cells will be ignored). 
// activate onmousedown event listener on cells within table with id="mainTable"
REDIPS.table.onmousedown('mainTable', true);
 
// activate onmousedown event listener on cells for tables with class="blue"
REDIPS.table.onmousedown('blue', true, 'classname');
Parameters:
{String|HTMLElement} el
Container Id. TD elements within container will have added onmousewdown event listener.
{Boolean} flag Optional
If set to true then onmousedown event listener will be attached to every table cell.
{String} type Optional
If set to “class name” then all tables with a given class name (first parameter is considered as class name) will be initialized. Default is container/table reference or container/table id.

{HTMLElement} row(table, mode, index)
Method adds / deletes table row. If index is omitted then index of last row will be set.
Parameters:
{HTMLElement|String} table
Table id or table reference.
{String} mode
Insert/delete table row
{Integer} index Optional
Index where row will be inserted or deleted. Last row will be assumed if index is not defined.
Returns:
{HTMLElement} Returns reference of inserted row or NULL (in case of deleting row).

split(mode, table)
Method splits marked table cell only if cell has colspan/rowspan greater then 1.
Parameters:
{String} mode
Split type: h – horizontally, v – vertically. Default is “h”.
{HTMLElement|String} table Optional
Table id or table reference.

  1. Hej, thanks for your great code.

    I hope you have a solution for my problem. In each table cell is a textarea with user input. If i load the table and init the REDIPS.table the table cells are empty. How can i keep the init content of table cell?

    Thanks

  2. Hello. Can you please make it clear, if I can use REDIPS.table library in my application, selling of which is planned? Thank you in advance.

  3. split function causing a loss of cell id
    i merge cell id 1 , 2 , 3 together
    but when split back it left only 1, null , null
    is there a way to avoid this? Thank you in advance.

  4. First of all, thanks for sharing this code with the community. It can save a lot of time for so many people.
    That being said, I ran into a problem. I searched for it before writing this comment in order to find a place address this but i could not find any.
    I want to maintain the width and height of the merged cells. if we take example 0 for instance io if we merge 0-0 with 0-1 and 1-0 with 1-1 and so on for every row then we will lose a column witch is expected but we lose the width of the merged cells as well.
    Can you eleborat on what is causing this or where do I start to fix this . thanks.

  5. Hi,
    when two columns are merged, lets say that referenced row is lost. In this moment it’s needed to recalculate new width of wider column. Or we can have simpler approach with row header that will preserve each column width. Here is simple modification of example0. To the index.html place new row:

    <thead>
    <tr>
        <td class="ignore"></td>
        <td class="ignore"></td>
        <td class="ignore"></td>
        <td class="ignore"></td>
        <td class="ignore"></td>
        <td class="ignore"></td>
        <td class="ignore"></td>
    </tr>
</thead>

    “.ignore” class name is a signal to the library to omit attaching onclick mouse event listener. And instead of div#myContainer td style, add the following:

    /* table cells */
td {
    border: 1px solid navy;
    height: 40px;
    width: 70px;
    text-align: center;
    padding: 2px;
}

/* set styles for header row */
.ignore {
    height: 1px;
    border: 0px;
}

    Header row can be set without content and with minimal height to be almost invisible.

    Hope this trick will be helpful.
    Cheers!
