Tabellen: Nach Überlauftext suchen und Zellenhöhe anpassen

Hi @jdh_gd, I've written a quick script to do that. It reads the height of the first body row and uses that to dictate the heights of all the other body rows. For example:

/**
 * Set table row heights to a factor of the row height
 * of first body row of table.

function main() {

    var doc = app.activeDocument;
    if (doc.selection.length == 0)
        return alert('Please select one or more tables and run script again.');

    var tables = getTables(doc.selection),
        rowHeight;

    tablesLoop:
    for (var i = 0; i < tables.length; i++) {

        rowsLoop:
        for (var r = 0; r < tables[i].rows.length; r++) {

            var row = tables[i].rows[r];

            if (row.rowType == RowTypes.HEADER_ROW)
                // ignore header rows
                continue rowsLoop;

            row.autoGrow = false;

            if (rowHeight == undefined)
                // get the row height of first body row of table
                rowHeight = row.height;

            row.height = rowHeight;

            cellsLoop:
            for (var c = 0; c < row.cells.length; c++)

                // if the cell overflows, expand it by master row height
                while (row.cells[c].overflows) {
                    row.height += rowHeight;
                    row.cells[c].recompose();
                }

Let me know if that is what you expected. - Mark
