Swapping columns in InDesign with a java script

[geirb9262873]

Hello,

I have a document with many tables with the same Table Style.

All the tables have two columns.

I have managed to make a java script (jsx) that can change the width of the two columns and applied this automatically to all the tables in the document.

Now, I would like to swap the two columns in every table in the document, so that the leftmost column becomes the rightmost one. 

If anyone has a few lines of code to accomplish this, it would be great.

With best regards from,

Geir Braathen

Hi @geirb9262873, I have previously written code to do this. See my answer here. Let me know if it works for you as the code is quite untested. (Also, sadly, it is more than just a few lines only!)

Edit: If you try my function, you would use something like this:

// swap first and second columns
moveRowOrColumn(table.columns[1], LocationOptions.BEFORE, table.columns[0]);

Hi Mark,

Thank you for your reply.

I would love to try your code, but I get a bit lost in the long script you link to, so I am not sure how to apply the one-liner you give here. I tried a bit, but I get error messages.

I am new to scripting in InDesign, so I depend on some complete script that works without too much tweaking. 

Cheers,

Geir

Ah I see. Not to worry. To use my code as it is (in the other post) delete these lines:

   /*
        example 1:
        duplicate first row after itself
    */
    var newRow = duplicateRowOrColumn(table.rows[0], LocationOptions.AFTER);
    // then convert to body row
    if (newRow != undefined && newRow.isValid)
        newRow.rowType = RowTypes.BODY_ROW;

But which tables do you want it to work with? Just the first selected table? All tables in a story? All in a document? I'll need to adjust the way the script gets the table(s) depending on what you want.

Hi again Mark,

Thank you for your quick reply.

I want to apply the swap to all the tables in the document.

All the tables are similar and of same Table Style. They all have two columns, but a varying number of rows. 

I hope I have explained clearly.  I will give it another try now with your last advice.

Cheers,

Geir

Hello again,

Quick feedback with good news!

It works on the first table, but not the rest of the tables.

I tried to put in some code to choose all tables, but I get an error.

If you find a way for this to work on all the tables, it would be fantastic.

Cheers,

Geir

Hi @geirb9262873, well done on giving it a go. Yes my script was only demonstrating on the first table. Here's what I'd like you to change to make it work for all tables:

1. remove all text between

function main() {

and this line

/**
  * Duplicate a table Row or Column

 and replace with this:

var doc = app.activeDocument,
    tables = doc.stories.everyItem().tables.everyItem().getElements();

for (var i = 0; i < tables.length; i++) {
    var table = tables[i];
    if (table.isValid)
        moveRowOrColumn(table.columns[1], LocationOptions.BEFORE, table.columns[0]);
}

and that should do it!

Hi Geir, Does this work?

var table=app.activeDocument.selection[0].tables[0];
swapColumns(table);


/**
* Swaps the first two columns of a table 
* @ param the table 
* @ return void 
*/
function swapColumns(t){
    var nc = t.columns.add(LocationOptions.BEFORE, t.columns[0]);
    var c = nc.cells
    var lc = t.columns[2].cells

    for (var i = 0; i < c.length; i++){
        c[i].properties = lc[i].properties
    };   
    t.columns[2].remove();
}

[m1b]

OMG @rob day! Using the "properties" property is brilliant! My script stupidly loops over them all! Nice one. 🙂

- Mark

Edit: I hope you don't mind, I edited my function to apply the properties the way you did, which is very convenient, but I also noticed that you then need to move the content in a more deliberate way, to ensure that text styles and graphics come with it correctly. (See my function.)

[rob day]

I hope you don't mind

No probelm.

Hi Rob,

Thank you for elegant little program.

However, I get an error message when I try to run it.

Maybe there is some additional code needed that I am not aware of.

I am quite new to scritping in InDesign. 

I attach a screen capture of the error message. 

Cheers,

Hi @geirb9262873, select a text frame with a table in it first and then run script. 
- Mark

[geirb9262873]

Hi Rob and Mark,

I got it.

One has to select a text frame. Then it works on the first table in that frame.

I would like to make it work on all the tables in the story (or the document, which has only one story).

What I will do now as a better than nothing solution is to do it page by page and select the text frame on that page.

I have expanded Rob's script with some additional lines like

var table=app.activeDocument.selection[0].tables[1];
swapColumns(table);

var table=app.activeDocument.selection[0].tables[2];
swapColumns(table);

var table=app.activeDocument.selection[0].tables[3];
swapColumns(table);

so then I get four tables in that frame fixed.

This is better than nothing.

Cheers,

Geir

Hi Geir, You can call my function from your table loop— you shouldn’t need to select anything.

This would loop over all the dcoument tables and call the swap function:

//all the document stories
var s = app.activeDocument.stories
for(var i=0; i < s.length; i++){  
    //the tables
    var t = s[i].tables;  
    for(var j=0; j < t.length; j++){  
        //call the function
        swapColumns(t[j])
    }  
}  



/**
* Swaps the first two columns of a table 
* @ param the table 
* @ return void 

*/
function swapColumns(t){
    var nc = t.columns.add(LocationOptions.BEFORE, t.columns[0]);
    var c = nc.cells
    var lc = t.columns[2].cells

    for (var i = 0; i < c.length; i++){
        c[i].properties = lc[i].properties
    };   
    t.columns[2].remove();
}

 on each table

Hi Rob,

Thank you so much. It works like a dream now. The script runs through the whole docuement and does its job perfectly. 

I am very happy about the quick and competent help I have received here. 

Is there is a guide or a text book that explains how to make jsx scripts in InDesign.

I am thinking about using Python, as I have some experience with that language for visualisation of scientific data. I think there is some sort of interface so that InDesign will understand code written in Python.

I wish you a lovely day.

Thank to Mark also for his answers and efforts.

All the best from,

Geir

[rob day]

I am thinking about using Python, as I have some experience with that language for visualisation of scientific data

The other options are Applescript and Visual Basic—no Python

But the JavaScript (ExtendScript) variables, functions, and loops should be familiar, so I’m guessing you want to learn ExtendScript.

You can get a PDF of Adobe’s Scripting Guide here:

https://usermanual.wiki/adobe/InDesigncs6ScriptingJSEN.3768967468/view

And an HTML guide with sample scripts here:

https://developer.adobe.com/console/servicesandapis

And a searchable well organized API is here:

Glad it's solved! Just a caveat on Rob's script—being beautiful and brief—if you had multiple text styles (eg. a word in italic) in the moved column it will be gone afterwards.

I have heard of someone using python to script Adobe products but when I looked into it they were basically using python to deliver javascript commands... so no, not a good option, sadly.

[rob day · Accepted solution]

(eg. a word in italic) in the moved column it will be gone afterwards.

Hi Mark, I wouldn’t be surprised if other problems pop up but the text formatting might be solved with a simple copy and paste after the properties have been set. This seems to work:

/**
* Swaps the first two columns of a table 
* @ param the table 
* @ return void 

*/
function swapColumns(t){
    var nc = t.columns.add(LocationOptions.BEFORE, t.columns[0]);
    var c = nc.cells;
    var lc = t.columns[2].cells;

    for (var i = 0; i < c.length; i++){
        c[i].properties = lc[i].properties;
        app.select(lc[i].texts[0])
        app.copy()
        app.select(c[i].texts[0])
        app.paste()
    };   
    t.columns[2].remove();
}

Yes exactly—that's a quick way to solve it, but... then the user's clipboard is changed.

Hi Mark,

you could use method duplicate() or move() on the source text.

Before you have to empty the target cell.

But be aware that there are perhaps graphic cells in your table!

Yes that's how I do it in my script. And graphic cells, too! There's always more to it when you set out to do a "quick script".
